Question: During the course of world war 1, 6.622 X 10^32 molecules of a poison gas called phosgene was fired on allied soldiers by german troops. To what mass does this correspond

Answer: The number of moles of phosgene is:

n = N(phosgene)/Nₐ, where Nₐ is an Avogadro constant (= 6.022*10²³ mol⁻¹), so n = 6.622*10³²/6.022*10²³ = 1.1*10⁹ mol.

The molar mass of phosgene is 98.92 g/mol

So, m (phosgene) = 1.1*10⁹ mole * 98.92 g/mol = 109*10⁹ g.
