Equation used:
Substitution into equation:
Answer (include units):

Answer 1

• n = 2.5 moles
• P = 0.6 atm
• T = 17°C
• R = 0.082

To Find:

• Volume of gas

Formula used:

• PV = nRT [ideal gas equation]

0°C = 273 K

So, 17°C = 290 K

Let the volume of gas be V

Using the formula, we get

0.6 x V = 2.5x0.082x290

V = 2.5x0.82x290/6

V = 99.08 Litres

So, volume of gas will be 99 litres approx.
