1. Convert the volume to millilitres
#"1 US fl oz = 29.57 mL"#
#"Volume" = 16 color(red)(cancel(color(black)("oz"))) × "29.57 mL"/(1 color(red)(cancel(color(black)("oz")))) = "473 mL"#
2. Calculate the mass of water
#"Mass of water" = 473 color(red)(cancel(color(black)("mL"))) × "1.00 g water"/(1 color(red)(cancel(color(black)("mL")))) = "473 g water"#
3. Calculate the moles of water
#"Moles of water" = 473color(red)(cancel(color(black)("g water"))) × "1 mol water"/(18.02 color(red)(cancel(color(black)("g water")))) = "26 mol water"#
