Answer Open in answr app 1mole=6.022×1023(Na=Avogadro′snumber) Thenumberofmoles=Avogadro′snumberGivennumberofmolecules Numberofmoles=6.022×10231.0505×1023 Number of moles =0.17 Now, to calculate mass, apply the formula: Numberofmoles(n)=Molarmass(M)Mass(m) We can write: Mass (m) = Number of moles (n) × Molar mass of CO2(M) Mass=0.17mol×44g/mol Mass=7.48g Thus, the mass of 1.0505×1023 molecule of CO2 is 7.48g.
