Answer:
Use the formula PV=nRT
P= 1.01 atm ( convert it into pascals)
P= 1.01×10^5
n= 0.00831
R= 8.314 ( it is a constant)
T= 25°C ( convert it into Kelvin)
T= 25+273
T= 298K
V= ?
Explanation:
PV=nRT
Arrange the formula
V= nRT/P
Put values,
V= 0.00831 × 8.314 × 298 / 1.01×10^5
V= 2. 03×10^-4 m^3
Now convert cubic meter into Litres
V= 2.03×10^-4 × 1000
V= 0.20L
