A 5.00g sample of a carbohydrate (compound containing carbon, hydrogen, and oxygen) is found to contain 2.006g carbon, 0.334g hydrogen, and 2.66g oxygen. What is the percent by mass of oxygen in the carbohydrate

Respuesta :

Answer:

percentage mass of oxygen = 53.2%

Explanation:

A sample of carbohydrate is 5.00 g . The carbohydrate contains carbon, hydrogen and oxygen . The

mass of carbon  = 2.006 g  

mass of   hydrogen = 0.334 g

mass of oxygen = 2.66 g

The total mass of the sample is 5.00 g which is the sum of the mass of the whole elements present in the compound.

percentage mass of oxygen = 2.66/5.00 × 100

percentage mass of oxygen = 266 /5

percentage mass of oxygen = 53.2

percentage mass of oxygen = 53.2%
