Question

A carpenter bought 90 nails. Each nail has a mass of 5.2 × 10 − 4 kilograms. What is the total mass, in kilograms, of the nails the carpenter bought?

Answer 1

To find the total mass of the nails the carpenter bought, we can simply multiply the number of nails by the mass of each nail:

Total mass = 90 x 5.2 x 10^-4 kg/nail

Total mass = 0.0468 kg

Therefore, the total mass of the nails the carpenter bought is 0.0468 kg.
