Question

Convert 150 grams of nitrogen to mols

Answer 1

n = 10.7142 /mol

Step-by-step explanation:

The formula for calculating mole is given as

n = m / M ----- (1)

Given data:

m = 150 g

M = 14g/mol

n = ?

Solution:

putting values in equation (1),

n = 150 g / 14 g/mol

n = 10.7142 /mol

Answer 2

150 g of nitrogen = 5.35 mol of nitrogen

The formula of nitrogen is N_2.

Molar mass = 2 × 14.007 g/mol= 28.014 g/mol

Moles of N_2 = 150 g N_2 × (1 mol N_2/28.014 g N_2) = 5.35 mol N_2
