Answer 1

for mass of nitrogen
first we find number of moles

Answer 2

Nitrogen gas is defined as N2.its molecular mass will become 28 .According to the mole concept in one mole there is 6.022×10^23 moles are present.so mass of one molecule of nitrogen gas 28/6.022×10^23.solve it then u get answer.
