Question

In 2018, the James H. Miller coal-fired power plant emitted 1.84 x 10⁸ kg of CO₂ per year. How many moles of CO₂ is emitted by this plant? (Molar mass of CO₂ is 44.01 g/mol)

a) 4.18 x 10⁶ moles
b) 8.35 x 10⁶ moles
c) 1.84 x 10⁸ moles
d) 4.18 x 10⁸ moles

Answer 1

To find the number of moles of CO₂ emitted by the power plant, convert the mass of CO₂ from kg to g and divide it by the molar mass of CO₂. The power plant emitted 4.18 x 10⁸ moles of CO₂ in 2018.

Step-by-step explanation:

To calculate the number of moles of CO₂ emitted by the James H. Miller coal-fired power plant in 2018, which was 1.84 x 10⁸ kg of CO₂ per year, we use the molar mass of CO₂. The molar mass of CO₂ is given as 44.01 g/mol. To find the number of moles, we first need to convert the mass of CO₂ from kilograms to grams:

1.84 x 10⁸ kg × 1000 g/kg = 1.84 x 10¹¹ g of CO₂

Next, we divide the total mass of CO₂ by its molar mass to find the number of moles:

1.84 x 10¹± g / 44.01 g/mol = 4.18 x 10⁸ moles

Therefore, the power plant emitted 4.18 x 10⁸ moles of CO₂ in 2018, which makes option (d) the correct answer.
