Acetaminophen is the generic name of the pain reliever in tylenol and some other headache remedies- the compoundhas the molecular formula c8h9n02. compute, to four significant figures, the mass percentage of each of the fourelements in acetaminophen.

The mass percentage of carbon element is 63.57 %, hydrogen element is 5.96 %, nitrogen element is 9.28 % and oxygen element is 21.19 %

Explanation:

We are given:

A chemical compound having chemical formula of . This compound is made by the combination of carbon, hydrogen, nitrogen and oxygen elements.

1 mole of acetaminophen contains 8 moles of carbon atom, 9 moles of hydrogen atom, 1 mole of nitrogen atom and 2 moles of oxygen atom

Mass of carbon element =

Mass of hydrogen element =

Mass of nitrogen element =

Mass of oxygen element =

Mass of the compound = 151 g/mol

To calculate the percentage composition of an element in a compound, we use the equation:

     ........(1)

Putting values in equation 1, we get:

Putting values in equation 1, we get:

Putting values in equation 1, we get:

Putting values in equation 1, we get:

Hence, the mass percentage of carbon element is 63.57 %, hydrogen element is 5.96 %, nitrogen element is 9.28 % and oxygen element is 21.19 %

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
