Suppose you have 1g of H2O and you want to convert that to moles. You multiply 1g by the inverse of molar mass to get the moles of H2O: 1g H2O *(1mol H2O/18g H2O)= 0.56 moles of H2O in 1g of H2O. You get 18g = 2(1.008)+1(16.00).

What is the molecular mass for heroin?
The molecular mass of Heroin is 369.41 grams/mol.
Grams per liter into moles per liter how to convert?
divide by the molecular mass, (units of gram per mol)
If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
How do you convert grams to moles using avogadros number?
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
How many grams are in 5.2 moles of magnesium sulfide?
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
How do you convert from molecular mass to grams per mole?
Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
Convert 1.3 moles of calcium to grams?
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
How can you convert from molecules to grams?
How many molecules are in 94 grams of sodium fluoride
How do you convert millimoles per liter to grams per milliliter?
First you divide by 1000 to convert to moles/litre. Then you find the molecular mass (add up atomic masses from the periodic table). Multiply moles per litre by the molecular mass and it is in grams per litre.
What is the molecular mass for heroin?
The molecular mass of Heroin is 369.41 grams/mol.
Grams per liter into moles per liter how to convert?
divide by the molecular mass, (units of gram per mol)
How many micrograms is 350 picomoles?
To convert grams to moles you need the molecular mass. Firstly you need to convert 350 picomoles to micromoles. 350/1,000,000 is 0.000350 micromoles. Then you multiply by the molecular weight of the compound.
How do you convert moles to pounds?
Use the Molar Mass of a compound to convert it to grams, then convert that pounds. 1.0 lb = 453.59 g 1.0 g = 0.00220 lb
If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
How do you convert mol.dm3 to g.dm3?
You look up the molecular mass of the corresponding substance - that tells you how many grams there are per mole. Then you multiply by that number.
How do you convert grams to moles using avogadros number?
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
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
