A label on an empty sample container reads 12.00 g. You add in a sample of a compound and mass the sample container obtaining 15
Maksim231197 [3]

The mass of the sample reported is 3.5465 g option e is correct.

Mass is the quantitative measure of the physical body.

The mass of the empty sample container is given as 12 g.

The mass of empty as well as sample containers is given as 15.5465 g.

Therefore, the mass of the sample will be given as :

Mass of sample = mass of a sample as well as empty containers - a mass of empty sample container

  = 15.5465 - 12

  = 3.5465 g

Therefore, the mass of the sample reported is 3.5465 g option e is correct.
