Question

5.2x10^-23 grams Nitrogen to atoms

Answer 1

Answer:

2.23 atoms

Explanation:

In this question, we first need to change the mass of Nitrogen to moles by using the formula;

mole = mass ÷ molar mass

Molar mass of Nitrogen = 14g/mol

Mass = 5.2x10^-23 grams

mole = 5.2x10^-23 ÷ 14

mole = 0.371 × 10^-23

mole = 3.71 × 10^-24 mol

Number of atoms in Nitrogen atom = 3.71 × 10^-24 mol × 6.02 × 10^23 atoms (avagadro constant)

= 22.3342 × 10^(-24+23)

= 22.33 × 10-¹

= 2.233 × 10°

= 2.23 atoms
