Question

Calculation of mass from mole.

calculate the mass of the following.

1. 0.3 mole of aluminum (Atomic mass of Al=27).​

Answer 1

Answer:

Number of moles =Mass of Al/Atomic mass of Al

Mass=No.of moles × atomic mass.

So, mass of Al = 0.3 × 27

= 8.1g.

Aluminium phosphate has a chemical formula of AlPO4 and has a molar mass of 122 approx. So if 1 mole of AlPO4 has a mass of 122g/mol then its 0.3 mol will have a mass of 36.6 gram.
