Final answer:
To determine the moles of carbon in 440 mg of CO2, convert 440 mg to grams, find the moles of CO2 using its molar mass, and use the fact that there is one mole of C in each mole of CO2, resulting in 0.0100 moles of carbon.
Step-by-step explanation:
To calculate how many moles of carbon are in 440 mg of CO2, we start by converting the mass of CO2 to grams, as 440 mg is equal to 0.440 grams. Next, using the molar mass of CO2 which is 44.01 g/mol, we can find the number of moles of CO2. To find the moles of C, we see that one mole of CO2 has one mole of C.
The series of conversions is as follows:
- 0.440 g CO2 × (1 mol CO2/44.01 g CO2) = 0.0100 mol CO2
- Since there's one mole of C in each mole of CO2, we then have 0.0100 mol C.
In conclusion, there are 0.0100 moles of carbon in a 440 mg sample of CO2.
