Chapter 3, Problem 126

A Freon leak in the air-conditioning system of a large building releases 12 kg of CHF2Cl per month. If the leak is allowed to continue, how many kilograms of Cl will be emitted into the atmosphere each year?

Verified step by step guidance
1
Identify the chemical formula of the compound: CHF2Cl.
Determine the molar mass of CHF2Cl by adding the atomic masses of each element: C, H, F, and Cl.
Calculate the mass percentage of Cl in CHF2Cl by dividing the atomic mass of Cl by the molar mass of CHF2Cl and multiplying by 100%.
Calculate the total mass of CHF2Cl released in a year by multiplying the monthly release (12 kg) by 12 months.
Determine the mass of Cl emitted by multiplying the total mass of CHF2Cl released in a year by the mass percentage of Cl.
