PROBLEM 108P

How many grams of oxygen are collected in a reaction where 235 mL of oxygen gas is collected over water at a temperature of 25 °C and a total pressure of 697 torr?

Step-by-Step Solution:
Step 1 of 3

Solution 108P

Given that

Volume of oxygen = 235 mL.

Temperature (T) =  25 °C .

Pressure (P) = 697 torr .

Simply use the ideal gas equation: PV = nRT

where:

P = pressure = 717 torr

V = volume = 235 mL or 0.235 L

n = unknown

R = gas constant = 0.08206 L*atm/mol*K

T = temperature = 25 C + 273.15 = 298.15 K

Since the gas constant R is expressed in L*atm/mol K, the pressure should also be expressed in atm. Convert...
