Given that 25.0 ml of mercury has a mass of 340.0 g, calculate (a) the density of mercury and (b) the mass of 120.0 ml of mercury.

Answer :

(a) The density of mercury is, 13.6 g/ml

(b) The mass of 120.0 ml of mercury is, 1632 grams

Explanation :

(a) Now we have to calculate the density of mercury.

Given :

Volume of mercury = 25.0 ml

Mass of mercury = 340.0 g

Formula used :

Therefore, the density of mercury is, 13.6 g/ml

(b) Now we have to calculate the mass of 120.0 ml of mercury.

As, 25.0 ml of mercury has mass = 340.0 g

So, 120.0 ml of mercury has mass =

Therefore, the mass of 120.0 ml of mercury is, 1632 grams

i think   the answer is c hope i'm right
