Question

calculate number 0f moles 6.022 ×1023 molecular of calcium​

Answer 1

Explanation:

1 mole of NH

3

​

 has 6.023×10

23

 molecules of NH

3

​

.

So, the mass of 6.023×10

23

 molecules of NH

3

​

. is the mass of 1 mole of NH

3

​

  i.e. molar mass of NH

3

​

.

Molar mass =14.01+3(1.01)=17.04 g
