Question

A 2-g sample of sucrose is 6.50% hydrogen. What is the mass percentage of hydrogen in 300 g of sucrose? Show all work to support your answer.

Answer 1

The mass percentage of hydrogen in 300 g of sucrose is 9.75%

From the question given above, we were told that:

2 g of sucrose contains 6.50% (ie 0.065) hydrogen

Thus, we can obtain the percentage of hydrogen in 300 g of sucrose as follow:

2 g of sucrose contains 0.065 hydrogen.

Therefore,

300 g of sucrose will contain = $\frac{300 * 0.065}{2}$ = 9.75% of Hydrogen.

Thus, 300 g of sucrose contain 9.75% of Hydrogen.
