Question

Calclulate the mass of one molecule of nitrogen in gram​

Answer 1

1 molecule of N2 / (6.022 x 10^23 molecules/ mol)

= 1.6605779 x 10^-24 mols

Molar mass of nitrogen: 14.01 g / mol

Mass = mols x molar mass

Mass = (1.6605779 x 10^-24 mols) x (14.01 g/mol)
Mass = 2.326 x 10^-24 g

Answer 2

for its one mole it is of 28gram. according to mole concept in one mole, there is 6.022*10^23 moles are present. so mass of 1 molecule of nitogen gas is 28/(6.022*10^23)
