Answer: 25.3g

Explanation:

The number of moles in chemistry is connected to the Mass and Molar mass of a compond through the following formular;

Moles = Mass (g) / Molar Mass (g/mol)

0.25 mol = Mass (g) / 101 g/mol

Make 'Mass' the subject of the formular;

Mass = 0.25 mol x 101 g/mol

= 25.25 approx 25.3g
