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
