Question

0.5 mole of nitrogen calculate mass from mole of atom

Answer 1

hence one mole nitrogen mass equal to 14 grams. So mass is. 5 mole nitrogen is 7 gm

Answer 2

As we know that 1 mole is equal to the molecular mass of that atom
1 mole of nitrogen= 14 g
0.5 mole of nitrogen= 14*0.5
                                =7g
