Work Step by Step

Avogadro's number $6.022\times10^{23} molecules/mol$ Convert to moles: $H_2O$: $6.02\times10^{23}\ molecules = 1.0\ mol$; $Br_2$: $3.01\times10^{23}\ molecules = 0.5\ mol$ Molar masses: $CO_2:44.01\ g/mol,\ HF: 20.01\ g/mol$ Number of moles: 22 g of $CO_2$: $0.50\ mol$ 30 g of $HF$: $1.50\ mol$ The largest number of moles is in 30 g of HF.
