Mass of sample = 10
Amount of substance = 1
Molar mass = 12.011*10 + 1.008*16 + 14.007*5 + 15.999*13 + 30.973761998*3 = 507.181
Moles in the sample mass = 10 / 507.181 = 0.019 716 8
Mass of that amount of substance = 1 * 507.181 = 507.181
Molecules in the sample mass = 0.019 716 8 * NA = 1.18737e+22

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

Molar mass = sum over elements of (atomic weight x number of atoms)
For C₁₀H₁₆N₅O₁₃P₃: 12.011 x 10 + 1.008 x 16 + 14.007 x 5 + 15.999 x 13 + 30.973761998 x 3 = 507.181286 g/mol
Moles = mass / molar mass; mass = moles x molar mass
Molecules = moles x 6.02214076 x 10^23 (the Avogadro constant, exact by definition)

Molar mass in grams per mole is numerically equal to the molecular mass in daltons, so this figure doubles as the molecular weight.

Atomic weights are the IUPAC 2021 standard values. Several elements have a range rather than a single value because isotope ratios vary between sources; the conventional single value is used here.

Composition by mass

Element	Atoms	Atomic weight	Contribution (g/mol)	Share of mass
Oxygen (O)	13	15.999	207.987	41.008 %
