Answer 1

Answer:

100%

Explanation:

Diamond is made up of pure carbon

Answer 2

Answer:

you can assume that the weight of the unknown sample is 100g ( since 75% C + 25% H = 100%). Thus,. weight of C = 75g weight of H = 25g ... atomic mass of C=12.01gmol ... What is the chemical formula of a diamond?

Explanation:

The percent composition of a compound is the percent of total mass made up by a specific ... the mass of a specific element by the total mass and then multiplying by 100. ... How can I calculate the mass percent of carbon, nitrogen and oxygen in ... Question #e25c7 ... 75g of potassium nitrate are dissolved in 150g of water.
