Explanation / Answer

Question 5

Moles of permagnetic acid = 25 x 3.15 /1000 = 0.07875 Moles

Moles of CO2 produced in this reaction = 0.07875 x 6 / 10 = 0.04725 Moles

Using the moles we can calculte the volume of CO2

PV= nRT

P = Pressure in atm                       V= Volume in Liter

n = no of moles               R = 0.0821 L atm K-1 Mol-1

T = Temperature in Kelvin

P = 98.6 K Pa = 0.9733 atm

V = ?

n = 0.04725 Moles

T = 273 + 23 = 296

V = 0.04725 x 0.08206 x 296 / 0.9733 = 1.18 Liter

Hence 1.18 Liter is correct answer
