Answer:

V = 80.65L

Explanation:

Volume = ?

Number of moles n = 5 mol

Temperature (T) = 393.15K

Pressure = 1520mmHg

Ideal gas constant (R) = 62.363mmHg.L/mol.K

According to ideal gas law,

PV = nRT

P = pressure of the ideal gas

V = volume the gas occupies

n = number of moles of the gas

R = ideal gas constant (note this can varies depending on the unit of your variables)

T = temperature of the ideal gas

PV = nRT

Solve for V,

V = nRT / P

V = (5 * 62.363 * 393.15) / 1520

V = 80.65L

The volume the gas occupies is 80.65L

AysviL [449]

Answer:

B) 1.65

Explanation:

See the image uploaded for the percent error formula

Work:

Theoretical Value - Accepted Value/Accepted Value * 100

= (24.7-24.3)/24.3 * 100

= 0.4/24.3 * 100

= 0.0164609053 * 100

= 1.64609053

Can be rounded to 1.65%
