Answer:

1.2 ×10∧23 molecules

Explanation:

Nitrogen is an element in the periodic table

The relative molecular mass of nitrogen is 14

To get the number of molecules present we 1st find the moles present

Moles = mass/relative molecular mass

2.8 ÷ 14 = 0.2 moles

One mole of any substance is always equal to the avogadro's number of particles 6.0 × 10∧23

Therefore

0.2 moles × 6.0 × 10∧23

= 1.2 × 10∧23 molecules
