Question

if one mole of nitrogen molecules weight 28 gram calculate the mass of one molecule of Nitrogen in grams​

Answer 1

Answer:

Since 1 mol of nitrogen contains 6.02 × 1023 molecules.

So according to given information, 6.022 × 1023 molecules of N2 weigh = 28 gm

So, 1 molecule of N2 will weigh = 28 / 6.022 × 1023 grams of N2

= 4.648 × 10-23 grams of N2
