The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
#moles = mass/molar mass mass = #moles*molar mass mass = .10 moles*(atomic weight of na+atomic weight of N+3(atomic weight of oxygen)
Conversion of a certain mass of a substance to moles requires knowing the molar mass. Molar mass is given in grams per mole. Dividing the known mass by the molar mass gives the number of moles.
Mol is an official unit of concentration in SI, not of mass.The transformation of a concentration expressed in mass per volume in a concentration in moles is at your choice.
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )

Calculating the mass of a product from the number of moles of reactants APEX
Stoichiometry is based on the fact that chemical reactions occur in ratios of moles of all substances. The problem is that there is no device that directly measures moles. We do have a device to measure mass, so molar mass is used in stoichiometric calculations to give results which are measurable.

The number of moles in the equation of B DIVIDED BY the number of moles in the equation of A ANSWER TIMES the molar mass of B OVER 1. A is the the known compound, B is the one your trying to find out.
Yes - it allows one to convert the stoichiometric ratios into mass ratios.
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.

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
