Question

calculate the mass of the following 3.011×10^23(3.011×10 to the power of 23) number of N2 molecule ​

Answer 1

Answer:

Molar mass of nitrogen is 14gm and half mole of nitrogen will have half the mass as that of molar mass. therefore this will have mass equal to 7gm. as 3.011*10^23 is half mole.

Answer 2

Answer:

3.011*10^23 is 1/2 mole of N2 molecule as 1 mole of N2 molecule consists of 6.022*10^23 molecules.

Therefore, number of mole=1/2

Molar mass=14*2=28g/mol

Mass=number of mole*molar mass

=1/2*28

=14g
