A container with a mass of 50g

Question

A container with a mass of 50g and a capacity of 100ml is filled with water. What is the total mass of the container and water ?

Answer 1

For this, we must find the mass of the water in the container and then add it to the mass of the container to find the total mass.

 

Using the density of water, we find the mass:

 

D = m/V

 

Therefore,

 

m = DV

 

Since the density of water is approximately 1 g/mL (it's about 0.972 but unless otherwise stated, I'll simplify to 1), and the V = 100mL, it follows that:

 

m = 100mL(1 g/mL)

 

m = 100g

 

Then we add the mass of the container:

 

100 + 50 = 150 grams
