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 0.999 999 999 65 (30) × 10 −3 kg⋅mol −1. 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.. M(H) 1.007 97 (7) × M u 1.007 97 (7) g/mol

The molar mass of titanium is approximately 47.88 g per mole or 47.8 atomic mass units. Because of the relationship between Avogadro's number and the molar mass, it can be inferred that for 7.88 g of titanium contains 6.022×10 to the 23rd atoms of titanium.
