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