Answer:

0.192 mol.

Step-by-step explanation:

  • To calculate the no. of moles of a substance (n), we use the relation:

n = mass / molar mass.

mass of AsH₃ = 15.0 g.

molar mass of AsH₃ = 77.95 g/mol.

∴ The number of moles in 15.0 g AsH₃ = mass / molar mass = (15.0 g) / (77.95 g/mol) = 0.192 mol.
