If a mass of a proton is `1.67xx10^(-27)kg`, how many protons will be present in 1 kg?
Given data:
Mass of a proton `=1.67xx10^(-27)kg`
`1.67xx10^(-27)kg` is mass of 1 proton.

Text Solution

Verified by Experts

1 kg is the mass of `1/(1.67xx10^(-27))` protons
`=0.5988xx10^(27)` protons
`=5.988xx10^(26)` protons
`=5.988xx0^(26)` protons
`5.988xx10^(26)` protons will be presnet in 1 kg.
