Combustion means the burning of something. So in the given question, you could say, “In this question, combustion means the burning of methane”.
A evole like a pokemon does to its environment.
Answer:
27.4 g/mol
Explanation:
Assuming the compound is a gas and that it behaves ideally, we can solve this problem by using the <em>PV=nRT formula</em>, where:
- V = 245 mL ⇒ 245 mL / 1000 = 0.245 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
<u>Inputting the data</u>:
- 1.22 atm * 0.245 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
<u>Solving for n</u>:
With the <em>calculated number of moles and given mass</em>, we <u>calculate the molar mass</u>:
- 0.334 g / 0.0122 mol = 27.4 g/mol
