How many molecules are in 15.2 L of CO3? Round your answer to the nearest hundredths place. _ molecules

Answer 1

Assuming CO3 is in STP, the stoichiometric expression would be 22.4L/1 mol of your molecule. You would start calculating using your single unit being 15.2 L.

15.2L CO3 x 1 mol CO3 x 6.022 x 10²³ molecules CO3 =. 4.09 x 10²³ molecules CO3

22.4 L CO3 1 mol CO3
