Question

A compound has 20% of carbon and the rest is hydrogen.if the amount of hydrogen in the compound is 160g,then find the amount of carbon and total amount of compound.​

Answer 1

carbon=32 ,total compound =192

Answer 2

Answer:

Let the amount of carbon =xg

Amount of carbon =20%

Amount of hydrogen=100%-20%=80%

Now given that the amount of hydrogen is 160g

Therefore the amount of compound is

$80\% \: of \: x = 160g \\ \frac{80}{100} \times x = 160g \\ x = \frac{160 \times 100}{80} = 200g$

Now amount of carbon is 20% of compound

$20\% \: of \: 200 = \frac{20}{100} = 40g$

Hence the amount of compound is 200g and the amount of carbon is 40g.
