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).
You have to first convert Kilos to grams. 1.42 kilos is 1420 grams. Next you have to find out the molecular weight (can be added up from the periodic table). Now divide grams by molecular weight to get your final answer in moles.
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
The molecular mass of Heroin is 369.41 grams/mol.
The molecular mass of cytosine is approximately 111.1 grams per mole.
To convert grams to moles, you need to divide the given mass (2.9 grams) by the molar mass of the substance. The molar mass of a substance can be found by adding up the atomic masses of all the atoms in a molecule.
To convert molecular weight from daltons to grams, you use the molar mass constant, which is 1 g/mol = 1 dalton. Therefore, the molecular weight in daltons is equivalent to the molar mass in grams per mole. Simply express the molecular weight in 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.
the answer to your question is 0.0004 g/mol.
Multiply the number of moles by the molecular weight.
To convert moles to pounds, you need to know the molar mass of the substance in grams/mol. Once you have the molar mass, you can convert moles to grams using the formula: moles x molar mass. Finally, you can convert the grams to pounds by dividing by 453.59 grams per pound.
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.
You have to first convert Kilos to grams. 1.42 kilos is 1420 grams. Next you have to find out the molecular weight (can be added up from the periodic table). Now divide grams by molecular weight to get your final answer in moles.
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
The molecular mass of Heroin is 369.41 grams/mol.
To convert micromoles (μmol) to grams, you need to know the molecular weight of the substance in question. The formula to convert is: grams = micromoles × molecular weight (g/mol) / 1,000,000. Once you have the molecular weight, simply multiply 5.67 μmol by the molecular weight and divide by 1,000,000 to get the result in grams.
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.
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
