Question

0.3 moles of aluminium calculate the mass

Answer 1

Answer:

Explanation:

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.

Answer 2

Answer:

12.74×10^-17

Explanation:

3×10^6=mole×6.022×10^23

mole=3×10^6÷6.022×10^23=0.49×10^-17

mole=mass÷molar mass

mass=mole ×molar mass

mass=0.49×10^-17×26=12.74×10^-17
