2. Find the Volume of 3.00 mol of gas whose temperature is 60.0 C and whose pressure is 5.00 L. 3. Find the tempature of 1.50 mol of gas whose pressure is 4.00 atm and whose volume is 7.50L
4. Find the number of moles of a certain ideal gas whose volume, tempature and pressure are 3.00 L, 25.0, and 2.00 atm, respectively
Please show work I will give you a 5 star review and much points

2. 16.4 L

3. 243.6K

4. 0.25mol

Explanation:

Using the ideal gas formula for the series of questions in this case, we have;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

QUESTION 2:

V = ?

P = 5 atm

n = 3 mol

T = 60°C = 60 + 273 = 333K

PV = nRT

5 × V = 3 × 0.0821 × 333

5V = 82.02

V = 82.02/5

V = 16.4 L

QUESTION 3:

P = 4 atm

V = 7.5L

n = 1.5mol

T = ?

PV = nRT

4 × 7.5 = 1.5 × 0.0821 × T

30 = 0.123T

T = 30/0.123

T = 243.6K

QUESTION 4:

P = 2.00 atm

V = 3L

n = ?

T = 25°C = 25 + 273 = 298K

PV = nRT

2 × 3 = n × 0.0821 × 298

6 = 24.47n

n = 6/24.47

n = 0.25mol
