Hint: The weight of a person is the product of their mass and the gravitational acceleration experienced by them. Their mass is independent of the gravitational acceleration but their weight does depend on it.
Formula used: In this solution, we will use the following formula:
Weight of a person: $W = mg$ where $m$ is the mass of the person and $g$ is the gravitational acceleration they experience.

$W = mg$
Since the gravitational acceleration on the moon has been given to us $= 1.63\,m/{s^2}$, the weight of the man on the moon will be
$W = 70 \times 1.63$
$\Rightarrow W = 114.1N$
Hence the weight of the man on the moon will be $114.1$ Newtons which is the actual unit of weight of the man.
