Question

Given that 20% of a compound is carbon and the rest is hydrogen. If the amount of hydrogen in the compound is 160 g, then find the amount of carbon and total amount of the compound​

Answer 1

Answer:

200

200÷100×20_Formula of percentage

Step-by-step explanation:

Answer 2

Answer: The amount of compound is 200g

              The amount of carbon is 40g

Step-by-step explanation:

Let the amount of compound = x g

Amount of carbon = 20%

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

Now given that the amount of hydrogen is 160 g

Therefore the amount of compound is

$80\% \text { of x} = 160 g\\\\\Rightarrow \dfrac{80}{100} \times x= 160g\\\\\Rightarrow x= \dfrac{160\times 100}{80} = 200g$

Now amount of carbon is 20% of compound

$20\% \text{ of 200} = \dfrac{20}{100} \times 200 = 40g$

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