What is the temperature of 12.20 mol of gas in a 18.35 l tank at 16.40 atm? round your answer to the tenths place.
Based on the calculations, the temperature of this ideal gas is equal to 300.5 K.
How to calculate the temperature.Mathematically, the temperature of an ideal gas is given by this formula:
[tex]PV=nRT\\\\T=\frac{PV}{nR}[/tex]
Where:
P is the pressure.R is the ideal gas constant.T is the temperature.n is the number of moles.V is the volume.Given the following data:
Number of moles = 12.20 moles.
Volume = 18.35 L.
Pressure = 16.40 atm.
Substituting the given parameters into the formula, we have;
[tex]T=\frac{16.40 \times 18.35}{12.20 \times 0.0821}\\\\T=\frac{300.94}{1.00162}[/tex]
T = 300.5 K.

Christopher runs a farm stand that sells apples and bananas. Yesterday christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163. 50. Today he sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76. 75. Determine the price of each pound of apples and the price of each pound of bananas
The equation computed shows that the price of apple is $2 and the price of banana will be $2.75.
How to compute the equation?Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. This will be:.
35a + 34b = 163.50
He also sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76.75. This will be:
15a + 17b = 76.75
Equate both equations
35a + 34b = 163.50 ..... i
15a + 17b = 76.75 ...... ii
Multiply equation i by 15.
Multiply equation ii by 35
525a + 510b = 2452.50 .... iii
525a + 595b = 2686.25 .... iv
Subtract equation iii from iv
85b = 233.75
b = 233.75/85
b = 2.75.
The price of banana is $2.75.
The price of apple will be:
35a + 34b = 163.50
35a + 34(2.75) = 163.50
35a + 93.50 = 163.60
35a = 163.50 - 93.50
35a = 70
a = 70/35
a = 2
The price of apple is $2.

The final temperature of the water after addition to the heated water at 20° C in degree kelvins' is calculated as; 295.23 K
What is the Final Temperature?We are given;
mass of the initial water; m₁ = 2.5 kg
specific heat capacity of water; c = 4189 J/kg.K
initial temperature of water; T₁ = 13.5 ⁰C
final temperature of the water; T₂ = 22.5 ⁰C
mass of the final water; m₂ = 0.5 kg
initial temperature of the final water; T₁,i = 20 ⁰C
If the system is isolated, then we have;
m₁*c*(T_f - T₂) + m₂*c*(T_f - T₁,i) = 0
c will cancel out to give;
[2.5T_f - (2.5*22.5)] + [0.5T_f - (0.5*20)] = 0
2.5T_f - 56.25 + 0.5T_f - 10 = 0

8-2 skills practice adding and subtracting rational expressions
The expressions 3/x + 5/y and 3/(8p^2r) + 5/(4p^2r) are algebraic expressions
The simplified expressions are (3y + 5x)/xy and 13/(4p^2r)
How to solve the rational expressions?From the complete question (see attachment), we have:
3/x + 5/y
Take the LCM
3/x + 5/y = (3y + 5x)/xy
Also, we have:
3/(8p^2r) + 5/(4p^2r)
Take the LCM
3/(8p^2r) + 5/(4p^2r) = (3 + 10)/(4p^2r)
Evaluate the sum
3/(8p^2r) + 5/(4p^2r) = 13/(4p^2r)
