Question

What is the mass of 2.50 moles of CO2?(1 point) Responses
88.02 g
44.01 g
12.01 g
110.025 g

Answer 1

To find the mass of 2.50 moles of CO2, you need to know the molar mass of CO2.

The molar mass of CO2 can be calculated as follows:
- Carbon (C) has a molar mass of approximately 12.01 g/mol.
- Oxygen (O) has a molar mass of approximately 16.00 g/mol, and there are two oxygen atoms in CO2.

So, the molar mass of CO2 is:
\[
12.01 \, \text{g/mol} + (2 \times 16.00 \, \text{g/mol}) = 12.01 \, \text{g/mol} + 32.00 \, \text{g/mol} = 44.01 \, \text{g/mol}
\]

Now, to find the mass of 2.50 moles of CO2:
\[
\text{Mass} = \text{Number of moles} \times \text{Molar mass}
\]
\[
\text{Mass} = 2.50 \, \text{moles} \times 44.01 \, \text{g/mol} = 110.025 \, \text{g}
\]

Therefore, the mass of 2.50 moles of CO2 is **110.025 g**. The correct response is:

**110.025 g**.
