(The molar mass of NutraSweet is 294.30 g/mol) Start with the number of grams of each element, given in the problem. If percentages are given, assume that the total mass is 100 grams so that; the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol = 1.000000 g/mol. For normal samples from earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight or the conventional atomic weight.

The molar mass of a substance is the mass of one mole of the substance. This collection of ten chemistry test questions deals with calculating and using molar masses. The answers appear after the final question. A periodic table is necessary to complete the questions.The number of atoms in a formula may be calculated using the weight of a sample, its atomic mass from the periodic table and a constant known as Avogadro’s number. Once molar mass is known, the original weight of the sample is divided by the molar mass then multiplied by Avogadro's number.
