Grams to Moles Step 1 Find the number of gramsof the substance. You will know from the problem how many grams and what the substance is, for example, 12 g of water. Step 2 Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the...
To do this, you have to look up the atomic weights in the periodic table or, to make things easier on yourself, you can use an online mole calculator that automatically converts between weight in grams and number of moles. Once you know the number of moles of each component of the ...
Continuing the example from the previous step, 0.13 moles of Ca(OH)2 corresponds to 0.13 x 2/1 = 0.26 moles of HCl. This represents the moles of HCl required to react with 10 grams of Ca(OH)2. Things Needed Periodic table of the elements Scientific calculator References State University ...

In order to determine the number of moles of a given compound, the first thing you need to do is find the molecular mass (or molecular weight) of the compound in question. Once you've done that, you need to determine how much the compound weighs physical
grams of sample = (molar mass) x (moles) Problem Find the number of grams in 0.700 moles of hydrogen peroxide, H2O2. Solution Calculate the molar mass by multiplying the number of atoms of each element in the compound (its subscript) times the atomic mass of the element from the periodic...
Add these values together foreach different atomin the molecule. This will give you themolecular massof the molecule. This is equal to the number of grams in one mole of the substance. Divide the number of grams of thesubstanceby the molecular mass. The answer will be thenumber of molesof...
