Answer
is: the final pressure of the gas is closest to 3,17 atm.

T₁ =
310 K.</span><span>
V₁ =
6 L.</span><span>
p₂ = ?</span><span>
T₂ =

V₂ = 8,0 L.</span><span>
<span>Use combined gas law - the volume of amount of gas is proportional to the ratio of
its Kelvin temperature and its pressure.</span><span>
p</span></span><span>₁V₁/T₁ =

Answer:
no. of moles = measured mass of substance/ molar mass of the constituted elements
Explanation:
No. of moles of 2.0g NaCl= 2/(23+35.5) = 0.034mol
For number 22. The answer is c. To find this look at the numbers before each compound O2 has no number which means 1, while CO2 has a 2 in front
1mol—44g/mol
0.10mol—x
x=0.10*44
x=4.4 g
The salt doesn't dissolve at that temperature. heating aids in dissolving
