A 20.0-g sample of sucrose contains 8.4 g of carbon. What is the mass percentage of carbon in sucrose? 42.00% 27.76% 68.00% 72.24%

To find the mass percentage of carbon in sucrose, we can use the formula: Given:- Mass of carbon = 8.4 g- Total mass of sucrose = 20.0 gPlugging in the values: Therefore, the mass percentage of carbon in sucrose is 42.00%.
