FAQ

What is the molar mass of Sr?

M(Sr) = 87.62 g/mol

How is the molar mass of strontium different from its atomic weight?

Only in units: the relative atomic mass Ar(Sr) = 87.62 has no unit, and the molar mass M(Sr) = 87.62 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Sr?

m = n × M = 2 mol × 87.62 g/mol = 175.24 g.
