Question

A flask contains 4.4 grams of carbon dioxide gas. Calculate:
a) How many moles of CO2 gas does it contain?
b) How many molecules of CO2 as are present in the sample?
c) How many atoms of oxygen are present in the given sample?

Answer 1

To calculate the molecules of CO2 present, you need to first covert from grams ofCO2 to moles of CO2 . ... After you covert to moles of CO2 , you then covert to molecules of CO2 with Avogadro's number; 6.022⋅1023 , ... You are given 4.4g CO2 , but this time we want atoms (ormolecules) of Oxygen gas
