What is the molecular formula for a compound that is composed of 54.53\% carbon 9.15\% hydrogen and 36.32\% oxygen the molecular formula mass is 88 g mol?

1 Expert Answer Thus the empirical formula is C2H4O. Multiply this by the mass of the elements with each subscript for a total of 44.02. Divide 132 by 44.02 to have 3 times the empirical formula for the moleular formula or C6H12O3.

What is the molar mass of the compound?

The molar mass of a compound is 88 g/mol. It contains 54.53\% carbon, 9.15\% hydrogen and 36.32\% oxygen. What is the molecular formula of the compound? | Socratic

How do you find the mole value of carbon and hydrogen?

That means that we have 86 grams of carbon and 14 grams of hydrogen. Next you want to convert these values to mole values since the subscripts denote mole values. Take the mass of each element and divide by the molar mass of that element.

What is the molar mass of 88G mol-1?

In this case, a molar mass of 88 g mol−1 tells you that one mole of this compound has a mass of 88 g. Use the percent composition of the compound to determine how many grams of each element you’d get in this 88-g sample.

What is the molecular weight of the compound C6H12O6?
