There is no direct relationship between atoms of boronand grams of boron. Use Avogadro's number to convert atoms to moles, and the atomic mass to convert moles to grams.
Since you are converting from atoms B, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of grams of B, so this goes in the numerator (on the top) of the last factor.
atoms B1.00 mole B10.8 gram = g B6.02E+23 atom B1.00 mole B
Note that the units atoms boron "cancel out" in the first factor and you are left in units of moles. Moles cancel outin the second factor and the final units are grams boron.

What would you multiply atoms of germanium by to get the units grams of germanium?
There is no direct relationship between atoms of germanium and grams of germanium. Use Avogadro's number to convert atoms to moles, and the atomic mass to convert moles to grams.Since you are converting from atoms Ge, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of grams of Ge, so this goes in the numerator (on the top) of the last factor.atoms Ge1.00 mole Ge72.6 gram= g Ge6.02E+23 atom Ge1.00 mole GeNote that the units atoms germanium "cancel out" in the first factor and you are left in units of moles. Moles cancel out in the second factor and the final units are grams germanium.
What are the major types of stoichiometry problems?
Conversions with units, especially getting atoms to moles to grams etc
What is the number of moles in 54 grams of aluminum?
For this you need the atomic mass of Al. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.54.0 grams Al / (27.0 grams) = 2.00 moles Al
How many nitrogen atoms are in 18.8 g of barium nitride?
Barium nitride is Ba3N2 (from the rules of ionic bonding). Its molar mass is 439 grams/mole (from the periodic table), so 18.8 grams of it is 0.0428 moles (by algebraic direct proportion). Multiply this by Avogadro's number (6.02x1023; the number of particles in 1 mole) and you get 2.58x1022 formula units of barium nitride, and there are 2 nitrogen atoms per formula unit, so double it to 5.16x1022 atoms of nitrogen.
How many moles are in 186 grams of HBr?
For this you need the atomic (molecular) mass of HBr. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. HBr= 81.0 grams186 grams HBr / (81.0 grams) =2.30 moles HBr
What would you multiply grams of oxygen by to get the units atoms of oxygen?
There is no direct relationship between grams of oxygenand atoms of oxygen. Use the atomic mass to convert grams to moles and Avogadro's number to convert moles to atoms.Since you are converting from grams O, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of atoms of O, so this goes in the numerator (on the top) of the last factor.g O1.00 mole O6.02E+23 atom O= atoms O16.0 gram O1.00 mole ONote that the units grams oxygen "cancel out" in the first factor and you are left in units of moles. Moles cancel out in the second factor and the final units are atoms oxygen.

How many grams do 4.4 x 1022 atoms of potassium weigh. answer in units of grams?
The mass is 2.86 grams but the weight will be 0.028 Newtons.
One mole of boron has a mass of how many grams?
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.

What is a conversion in math?
A conversion is the change between two units (usually units of measurement). For example... if you have 2 kg and you want to find out how many grams are in it, you multiply by the amount of grams there are in ONE kilogram, 1000. Therefore, 2 times 1000 is 2000 grams.
How do you Convert 1.18 gram to atomic mass unit?
1 gram = 6.0221415 × 1023 atomic mass units, so multiply grams by 6.0221415 × 1023 1.18 grams = 7.10612697 × 1023 atomic mass units
How do I convert 38 grams of NaCl to moles and formula units?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams38.0 grams NaCl / (58.5 grams) = .650 moles NaCl
What is the mass in grams of 1.501023 atoms Mg?
This can be found using one of the most important constants for chemistry: Avogadro's number. According to wikipedia, the standard atomic weight of magnesium is 24.3050 grams per mole. Using Avogadro's number, we know there's 6.0221415 × 1023 atoms per mole, so if you divide the standard atomic weight of magnesium by Avogadro's number, you can get number of grams per atom of magnesium (i.e. the mass of a single magnesium atom in grams). (24.3050 g/mole) / (6.0221415 x 1023 atoms/mole) = 4.03564 g/atom
