Question

What is the mass of carbon in 69.00 mg of co2

Answer 1

18.82 mg

Step-by-step explanation:

From the given information:

The molar mass of CO2 is calculated as follow

= (12 + (16 ×2))

= 44

The mass of carbon is determined by dividing the mass no of carbon from co2 by the molar mass of CO2, followed by multiplying it by 69.00 mg

=
`((12)/(44)* 69 )`

=(0.2727 × 69 )

= 18.82 mg
