Answer:
0.208 mol
Explanation:
Assuming the gas sample behaves like an ideal gas, we can solve this problem by using the following formula:
Where:
- R = 0.082 atm·L·mol⁻¹·K⁻¹
We<u> input the data</u>:
- 0.857 atm * 115 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 250 K
And <u>solve for n</u>:
Mass=density x volume, i.e. 1.03 x 85.32 = 87.88 g
