Reduces from birth till old age is the answer because if you look at the chart, you can see that both the percentages and hours of total sleep time decrease as humans get older.
2.2311 moles of gas are there in a 50. 0 l container at 22. 0 °c and 825 torrs.
<h3>What is an ideal gas?</h3>
An Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
Assuming the gas is ideal, we can solve this problem by using the following equation:
PV = nRT
Where:
P = 825 torr ⇒ 825 / 760 = 1.08 atm
V = 50 L
n = ?
R = 0.082 atm·L·mol⁻¹·K⁻¹
T = 22 °C ⇒ 22 + 273.16 = 295.16 K
We input the data:
1.08 atm x 50 L = n x 0.082 atm·L·mol⁻¹·K⁻¹ x 295.16 K
And solve for n:
24.20312
n = 2.2311 mol
Hence, 2.2311 moles of gas are there in a 50. 0 L container at 22. 0 °c and 825 torrs.

the answer is C, natural gas.. hope it helps
Answer:
0.890 L
Explanation:
P1V1 = P2V2
P1 = 1.00 atm
V1 = 3.56 L
P2 = 4.00 atm
V2 = ?
Solve for V2 --> V2 = P1V1/P2
V2 = (1.00 atm)(3.56 L) / (4.00 atm) = 0.890 L
