Question

a beaker weighs 120g when empty and 200g when filled with
kerosene.Find the volume of the beaker.the density of kerosene is 800kg/cubic metre

Answer 1

I hope it is correct answer

Answer 2

Explanation:

Explanation:

Given : -

• Total mass =200g

• Mass of beaker (beaker weighs when empty) =120g

• Density of the kerosene is 800kg/m3

To Find : -

• Find the volume of the beaker.

Solution : -

Mass of kerosene =Total mass-mass of the beaker

=200 - 120g

= 80g

The formula for the density is

Density of kerosene = Mass/volume

From this formula we can find the volume of kerosene

Mass/density =Volume of kerosene

80/0.8 = 100ml ³

Volume of kerosene is 100ml

So the volume of the kerosene is 100ml
