Question 5 (1 point) A protein has an empirical formula of C3H3O4. Proteins can have a very high molecular mass. In this case, the molecular mass for the protein is 1,649.94 g/mol. What number do all the subscripts in the empirical formula need to be multiplied by to determine the molecular formula of the compound? C = 12.01 g/mol H= 1.01 g/mol O=16.00 g/mol Do not use significant figures. Round your answer to a whole number (no decimals). Ex: If your answer were 2.5, you would write 3. There will be no units. 4 Your Answer: Answer
