The pressure of a gas sample at 60.0 °C is decreased from 3.40 atm to 2.60 atm by cooling at a constant volume. What is the temperature (in °C) of the gas at 2.60 atm?
When the pressure of a gas is decreased from 3.40 atm to 2.60 atm, the temperature of the gas will decrease from 60.0 degree celsius to 45.88 degree celsius.
What is Gay-Lussac law?Gay -Lussac law states that the pressure and temperature is in direct proportions. Thus, pressure increases with an increase in temperature. The relation can be mathematically expressed as follows:
P/T = a constant. Hence,
P1/T1 = P2/T2
The initial pressure of the sample is given, 3.46 atm and the initial temperature is 60 °C. The final temperature of the gas when gas the expand to the lower pressure of 2.60 atm is calculated as follows:
[tex]T_{2} = \frac{P_{2}T_{1}}{P_{1}}[/tex]
= (60 °C× 2.60 atm) / 3.40 atm
= 45.88 °C.
Hence, the final temperature of the gas which is expanded from the pressure of 3.40 atm to 2.60 atm with an initial temperature of 60 °C is 45.88 °C.

A sample of no2 occupies 16,500 ml at stp. How many no2 molecules are in the sample?.
According to Avogadro's law equal volume of all gases at the same temperature and pressure contain equal number of molecules. At STP one mole of any gas behaving ideally occupies a volume of 22.414 L.
What is molar volume?The volume occupied by one mole of a substance at a given temperature and pressure is defined as the molar volume at that temperature and pressure. The value of molar volume of an ideal gas at STP is important in stoichiometric calculations.
At STP, the number of molecules of a gas is given as:
Number of molecules of a gas (N) = V₀ in L / 22.414 × 6.022 × 10²³
Here V₀ in L = 16500 = 16.5 L
N = 16.5 / 22.414 × 6.022 × 10²³
N = 4.433 × 10²³
Thus the number of molecules present is 4.432 × 10²³.

What is the pressure in a 8.00 L tank with 50.5 grams of chlorine gas at 365 K?
The pressure in a 8.00 L tank with 50.5 grams of chlorine gas at 365 K is 2.67atm.
How to calculate pressure?The pressure of a given mass of gas can be calculated using the following formula:
PV = nRT
Where;
P = pressureV = volumeT = temperaturen = no of molesR = gas law constantThe number of moles in 50.5g of Chlorine gas is as follows:
moles = 50.5/70.91
moles = 0.71mol
P × 8 = 0.71 × 0.0821 × 365
8P = 21..34
P = 21.34/8
P = 2.67atm

1. -A mixture of aluminum metal and chlorine gas reacts to form aluminum chloride (AlCl3): 2Al(s) +
3Cl2(g) → 2AlCl3(s). How many moles of aluminum chloride will form when 5 moles of chlorine gas react
with excess aluminum metal?
Answer:
3.33 moles
Explanation:
We know that our limiting reactant is chlorine so we just have to figure out how much of the product aluminum chloride (AlCl3) would be formed from 5 moles of chlorine gas. As we can see in the balanced equation, the mole ratio of chlorine gas (Cl2) to aluminum chloride is 3:2 based on the coefficients of the species. All you have to do from here is divide the amount of moles of chlorine gas by its own coefficient and then multiply the number you receive by the coefficient of AlCl3.
