Question

Ozone (o3) is a highly reactive gas which is formed in the stratosphere with the help of ultraviolet radiations. if 10.5 moles of ozone gas is formed in the stratosphere, then its mass in grams will be (note: o 16 8 )

Answer 1

To calculate the mass of 10.5 moles of ozone gas, multiply the number of moles by the molar mass of ozone (48 g/mol), resulting in 504 grams.

Step-by-step explanation:

The student asked how to calculate the mass in grams of 10.5 moles of ozone gas (O3). To do this, we first need to know the molar mass of ozone. Since ozone is a molecule composed of three oxygen atoms and the atomic mass of oxygen is approximately 16 atomic mass units, we can calculate the molar mass of ozone as follows:

Molar mass of O3 = 3 × 16 g/mol = 48 g/mol

Now, to find the mass of 10.5 moles of ozone, we use the formula:

Mass (g) = number of moles × molar mass (g/mol)

Mass of O3 = 10.5 moles × 48 g/mol = 504 grams

Therefore, the mass of 10.5 moles of ozone gas is 504 grams.
