Question

Calculate the no of moles in 44.8 liters of co2 at STP

Answer 1

atomic mass of C is 12
atomic mass of O2 is 32
therefore molecular mass of CO2 is 44
no. of moles = mass of CO2÷molecular mass of CO2
no. of moles=44.8÷ 44
=1.081
approx 1
no of moles in 1 is 6.022×23 power of 10
hence moles in 44.8 is 1.081×6.022×23 power of 10 is right answer

Answer 2

Answer:

2 moles

Explanation:

Volume = 44.8 litres

MolarVolume = 22.4 L/mol

numberofmoles = Volume/MolarVolume

                          = 44.8/22.4

                          = 2 moles
