Mass % of nitrogen = mass of nitrogen*100 / total mass

= 14*100 / (1+ 14 + 32)

= 14*100 / 47
= 29.7 %

Why can you never see the far side of the mood from earth?

Answer: -

C) because the moon rotates once on its axis in the same time that it takes to revolve around the earth

Explanation: -

The moon rotates about it's axis one full time at about the same time as it takes to rotate around the earth.

This leads to only one side of the moon always appearing to Earth, called the near side.

One side of the moon is always not seen from the earth. It is called the far side of the moon.

Thus we can never see the far side of the moon because the moon rotates once on its axis in the same time that it takes to revolve around the earth
