Question

1. Calculate molar mass of N2 2. calculate mass of 0.5 moles of N2 gas. 3. calculate mass of 0.5 moles of N atom 4. calculate mass of 3.011*10²³ no. of an atom 5. calculate mass of 6.022*10²³ no. of N2 molecules plzz tell me about these questions plzzzz

Answer 1

1.)N = 14g
N2= 28g

2.) 1 mole of N2 gas = 28g
so 0.5 mole= 0.5×28
=14g

3.) 1 N = 14g
so 0.5 N = 0.5×14
=7g

4.) Mass of 3.022*10^23 N atom:-
1 atom= 14g= 6.022*10^23 number
1= 14/6.022*10^23
so 3.022*10^23 = 14/3.022*10^23

5.) 6.022*10^23 no. of N2 molecules = 28 g
