A sample of iron oxide has a mass of 1.596 g. On analysis it was found to contain 1.116 g of iron and 0.48 grams of oxygen. Find the percentage composition of this compound?

The total mass of the iron oxide is 1.596 g. The percentage composition by mass of iron is (1.116 g / 1.596 g) x 100% = 70%. The percentage composition by mass of oxygen is (0.48 g / 1.596 g) x 100% = 30%. So, the compound is 70% iron and 30% oxygen.


How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?

To calculate the theoretical mass percentage of oxygen in potassium chlorate, you would use the formula weight of oxygen divided by the formula weight of the compound (potassium chlorate) multiplied by 100. The formula weight of oxygen is 16.00 g/mol and the formula weight of potassium chlorate (KClO3) is 122.55 g/mol. So, (16.00 g/mol / 122.55 g/mol) * 100 = 13.06%.


What is the percentage composition of silicon dioxide?

Silicon dioxide is composed of 46.7% silicon and 53.3% oxygen by mass.


What percentage by mass of table sugar is hydrogen?

Table sugar (sucrose) has a molecular formula of C12H22O11, which means it is composed of carbon, hydrogen, and oxygen. To calculate the percentage by mass of hydrogen in table sugar, divide the mass of hydrogen by the total mass of the compound and then multiply by 100. In this case, hydrogen has a total mass of 22 g/mol out of a total molecular mass of 342 g/mol, which gives a percentage of approximately 6.4% hydrogen by mass in table sugar.
