5. The stratosphere contains approximately 3 billion kilograms of ozone, Os. How many moles of ozone is this? solve everything step by step cancelation to cancelation gen chem
Accepted Answer
To calculate the number of moles of ozone, we'll use the following steps:
1. Convert kilograms to grams:
3 billion kilograms = 3 x 10^9 kg
1 kg = 1000 g
3 x 10^9 kg
(1000 g / 1 kg) = 3 x 10^12 g
2. Find the molar mass of ozone (O3):
Molar mass of oxygen (O) = 16 g/mol
Molar mass of ozone (O3) = 3
16 g/mol = 48 g/mol
3. Calculate the number of moles:
Moles = Mass / Molar mass
Moles = 3 x 10^12 g / 48 g/mol = 6.25 x 10^10 mol
Therefore, there are approximately 6.25 x 10^10 moles of ozone in the stratosphere.
