Question

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%

Answer 1

Based on these percentages it is most likely 43% based on the ratio of the two elements.

Answer 2

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

Step-by-step explanation:

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

`\text{Mass percent of element}=\frac{\text{Mass of element in compound}}{\text{Mass of the compound}}* 100`

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:

`\text{Mass percent of carbon}=(48g)/(112g)* 100\\\\\text{Mass percent of carbon}=43\%`

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