3.A 134.50 g sample of aspirin is made up of 6.03 g of hydrogen, 80.70 g of carbon, and 47.77 g of oxygen. What is the percent by mass of each element in aspirin?

The percentage of mass of hydrogen in aspirin is 4.48%

The percentage of mass of carbon in aspirin is 60%

The percentage of mass of oxygen in aspirin is 35.5%

Explanation:

Given that,

Mass of sample of aspirin = 134.50 g

Mass of hydrogen = 6.03 g

Mass of carbon = 80.70 g

Mass of oxygen = 47.77 g

We need to calculate the percentage of mass of hydrogen in aspirin

Using formula for percentage of mass

Put the value into the formula

We need to calculate the percentage of mass of carbon in aspirin

Using formula for percentage of mass

Put the value into the formula

We need to calculate the percentage of mass of oxygen in aspirin

Using formula for percentage of mass

Put the value into the formula

Hence, The percentage of mass of hydrogen in aspirin is 4.48%

The percentage of mass of carbon in aspirin is 60%

The percentage of mass of oxygen in aspirin is 35.5%

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
