Question

PLEASE HELP!! DIMENSIONAL ANALYSIS AND MOLE CONVERSIONS CHEMISTRY!!

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

Please help me show work as well!

Answer 1

7.24 Litres

Step-by-step explanation:

Density of a substance can be calculated as follows;

Density (g/mL) = mass (g) ÷ volume (mL)

According to the given information, mole of N2 = 0.30moles, density = 1.16 g/ml.

Mole = mass ÷ molar mass

Therefore, mass = molar mass × mole

Molar mass of N2 = 28g/mol

Mass = 28 × 0.3

Mass = 8.4g

Volume = mass/density

Volume (L) = 8.4/1.16

Volume = 7.24 Litres
