Phenylpyruvic acid is produced in the body of abnormal amounts as the result of a molecular disease called phenylketonuria, which causes irreversible brain damage. phenylpyruvic acid is composed of 65.85% c, 4.91% h, and 29.24% o. what is its empirical formula? 1. cho3 2. c66h5o29 3. c3h3o 4. c6h5o2 5. c9h10o3 6. c3h2o 7. c9h8o3

6. C3H2O

Explanation:

C= 12.0107; H= 1.00797; O=15.9994

We calculate:

C= 65.85/12.01=5.48

H= 4.91/1.00=4.91

O=29.24/16.00= 1.82

Later, we divide among the smaller quantity

C=5.48/1.82= 3.01

H=4.91/1.82= 2.70

O=1.82/1.82=1

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
