Four moles of carbon monoxide (co) has 48 grams of carbon (c) and 64 grams of oxygen (o). what is the percent composition of carbon in carbon monoxide?

6.25%

8.3%

43%

75.0%

The percent composition of carbon in carbon monoxide is 43 %.

Explanation:

To calculate the mass percent of an element in a compound, we use the equation:

We are given:

Mass of compound = (48 + 64) g = 112 g

Mass of carbon in carbon monoxide = 48 grams

Mass of oxygen in carbon monoxide = 64 grams

Putting values in above equation, we get:

Hence, the percent composition of carbon in carbon monoxide is 43 %.
