Question

a tin containing 5000cm>3 of paint has a mass of 7kg.if the mass of the empty tin including the lid is 0.5kg calculate the density of the paint in g/cm>3.​

Answer 1

Answer:

1.3 g/cm³

Explanation:

The mass of the paint without the tin or lid is:

7 kg − 0.5 kg = 6.5 kg = 6500 g

Density is mass per volume:

d = 6500 g / 5000 cm³

d = 1.3 g/cm³

Answer 2

The density of the paint should be 1.3g/cm^3.

Given that,

• The tin contains 5000cm^3 of paint.
• And, the mass of 7 kg.
• Also, there is the mass of the empty tin including the lid is 0.5kg.

Based on the above information, the calculation is as follows:

The mass of the paint not considering the tin or lid should be

= 7 kg - 0.5 kg

= 6.5 kg

= 6500 g

Now the density should be

$d = 6500 g \div 5000 cm^3$

= 1.3 g/cm^3

Therefore we can conclude that the density of the paint should be 1.3g/cm^3.
