What value should be reported for the total mass of three samples of iron weighing 117.0 g, 19.43 g, and 6.1043 g?
AURORKA [14]

The value that should be reported for the total mass of three samples of iron will be 0.143 Kg or 143 g

<h3>What is Mass and Weight ?</h3>

Mass is the quantity of matter. While weight is a gravitational pull on an object. Mass is measured in Kg while weight is measured in Newton.

What value should be reported for the total mass of three samples of iron weighing 117.0 g, 19.43 g, and 6.1043 g?

The total mass will be the sum of the three masses.

The total mass = 117 + 19.43 + 6.1043

The total mass = 142.5343 g

Convert gram to kilogram by dividing the answer by 1000

The total mass = 142.5343/1000

The total mass = 0.1425343 Kg

Therefore, the value that should be reported for the total mass of three samples of iron will be 0.143 Kg or 143 g approximately
