Question

molar mass if nitrogen is 14u . what will be the mass of one atom of nitrogen in grams

Answer 1

Therefore 14 amu is 14 x 1 gram divided by Avogadro's Number. The atomic, not molar mass of nitrogen is 14U.

Answer 2

Answer: $2.32\times 10^{-23}g$

Explanation: According to avogadro's law, 1 mole of every substance contains $6.023\times 10^{23}$ particles and weigh equal to the molar mass of the substance.

Given molar mass of nitrogen = 14u = 14g

Thus $6.023\times 10^{23}$ atoms of nitrogen weigh= 14 gram

1 atom of of nitrogen will weigh=$\frac{14}{6.023\times 10^{23}}\times 1=2.32\times 10^{-23}g$
