Question

17. If one mole of nitrogen molecules weighs 28 g, calculate the mass of one molecule of nitrogen in grams
​

Answer 1

Answer:

1mole of nitrogen molecule - 6.022×1023

1 mole of nitrogen molecule - 28g

so,6.022×1023 molecules-28 gram

thus,6.022×102328 is mass of one molecule

Hence 4.6×10−23 is mass of molecule of nitrogen
