Question

What is the mass of a 5 mol sample of air? (M 29 g/mol) Mass of Air =Number grams

science chemistry

Answer 1

Answer #1

molar mass of air = 29 g/mol
number of mols of air = 5 mol

According to mol concept 1 mol of particles has mass= molar mass in grams
so 1 mol air = 29 g
therfore 5 mol air has mass= 5*29 = 145 g

mass of air = 145 g
