Question

Given the following set of values, calculate the unknown quantity P = 1.01 atm V = x (ANSWER = 0.20L) n = 0.00831 T = 25 ℃

Answer 1

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
