Question

calculate the mass of 0.5 mole of nitrogen atom

Answer 1

Mass of 1 Mol of N atom = 1 gram atom of N atoms = 14g

So mass of 0.5 Mol of N atoms =14*0.5 g
=7g.

Hope it's helpful to u.

Answer 2

The mass of 0.5 mole of nitrogen atom is 7 g.

Explanation:

• To calculate the exact mass of the 0.5 moles in nitrogen we have to know the total molar mass in the element of nitrogen.

• The number of the moles is equivalent to the given mass which is then divided by the total molar mass.

• Therefore in order to find the given mass, we will have to multiply the molar mass with the number of moles of element of nitrogen which are given to us.

• Therefore$mass = number of moles \times molar mass.$

• The molar mass of element nitrogen is equivalent to 14 g/mol. Therefore $0.5mol \times 14g/mol = 7g.$ .
