Question

The mass of a cylinder filled with gas is 30kg 250g and the mass of the empty

cylinder is 14kg 480g. How much is the mass of the gas contained

in it?​

Answer 1

Given:-

• Mass of a cylinder filled with gas = 30kg250g
• Mass of the empty cylinder = 14kg480g

To Find:-

• How much mass of the gas contained in it

Solution:-

we know that,

$\: \: \sf \: 1 \: kg = 1000g$

As given in the question,mass of the gas which filled in cylinder = 30kg250g

Now we will convert gram into kg

$\: \: \: \: \sf \: : \implies \: 30kg250g = 30kg \times \frac{250}{1000} \\ \\ \: \: \: \sf \: : \implies \: 30.25kg$

As given in the question,mass of empty cylinder = 14kg480g

Now we will again convert gram into kg

$\: \: \: \sf \: : \implies \: 14kg480g = 14kg \times \frac{480}{1000} \\ \\ \: \: \: \sf \: : \implies \: 14.48kg$

After converting gram into kg

Now we will find

mass of the gas contained in the cylinder

= 30.25kg - 14.48kg

= 15.77kg

= 15kg770g
