Answer to Question #167076 in General Chemistry for Kevin

Question

Convert 0.30 moles of nitrogen gas into liters of nitrogen gas if density of N₂ is 1.16 g/ml

Answer 1

Molar mass of nitrogen gas (N2) = 28 g/mol

So, mass of 0.30 mole nitrogen = (28 g/mol)×0.30mol

= 8.4 g

Volume of 0.30 mole nitrogen = (mass of 0.30 mole nitrogen/density of nitrogen)

= 8.4 g/(1.16 g/ml)

= 5.25 ml

So, volume of 0.30 mole nitrogen gas = 5.25 ml
