Because The temperature of our hand could be hot and it could be melting the smoothie
The volume of 0.98 mol oxygen gas at 275 k and a pressure of 2.0 atm is 11.06L.
<h3>How to calculate volume?</h3>
The volume of a given mass of gas can be calculated using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- R = gas law constant
- T = temperature
- n = number of moles
According to this question, 0.98 moles of oxygen gas at 275 k contains a pressure of 2.0 atm. The volume is calculated as follows:
2 × V = 0.98 × 0.0821 × 275
2V = 22.13
V = 11.06L
Therefore, the volume of 0.98 mol oxygen gas at 275 k and a pressure of 2.0 atm is 11.06L.

how would it be possible to even be absorbed?? the answer is released.
Answer:
2.19moles
Explanation:
mole = mass ÷ molar mass
Molar Mass of the compound, C135H96O9NS =
12(135) + 1(96) + 16(9) + 14 + 32
= 1620 + 96 + 144 + 14 + 32
= 1906g/mol
Next, we calculate the mass percent of Oxygen in the compound
O9 = 16(9) = 144g/mol
144/1906 × 100
= 0.0755 × 100
= 7.55%
This means that there are 0.0755g of Oxygen in 1 mole of the coal compound.
Hence, in 29.1 moles of coal, there would be 29.1 × 0.0755
= 2.19moles of Oxygen
