The mass percentage of carbon in sucrose can be calculated by dividing the mass of carbon by the total mass of sucrose and then multiplying by 100. In this case, the mass percentage of carbon in sucrose would be (8.4 g / 20.0 g) x 100 = 42%.
23 out of 42 as a percentage is about 54.762%.
The compound with 42% chlorine by mass is titanium tetrachloride (TiCl4). It has 42% chlorine because the molar mass of chlorine is 35.5 g/mol and the molar mass of TiCl4 is 189.68 g/mol, giving a chlorine mass percentage of 42%.
