Leroy Armstrong · Answer 1

To solve for the uncertainty of your mass in kilograms, simply multiply your total mass with the percent uncertainty.

We know that 4% = 0.04, therefore:

uncertainty = 60 kg * 0.04

uncertainty = 2.4 kg

However since uncertainty covers the upper and lower region, therefore correct answer must be:

± 2.4 kg
