Calculate the percentage by mass of the indicated element in the following compounds. hydrogen in ascorbic acid, hc6h7o6, also known as vitamin c. express your answer using two significant figures

The mass percent of hydrogen in ascorbic acid is 4.5 %

Explanation:

In , there are 6 carbon atoms, 8 hydrogen atoms and 6 oxygen atoms.

To calculate the mass percent of element in a given compound, we use the formula:

Mass of hydrogen =

Molar Mass of ascorbic acid =

Putting values in above equation, we get:

Hence, the mass percent of of hydrogen in ascorbic acid is 4.5 %.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
