The number of moles of carbon in a sample of C4H10 that also contains 200 g of hydrogen is 80 moles.
The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.
According to this question, a sample of C4H10 was given meaning that the ratio of carbon to hydrogen is 4:10.
If 200 g of hydrogen is contained in the sample, then 200 × 4/10 = 80g of carbon is present.
no of moles of C = 80
Therefore, the number of moles of carbon in a sample of C4H10 that also contains 200 g of hydrogen is 80 moles.
