M=D*V
D=10.5 g/cm³
V=42.5 cm³
m= 10.5 g/cm³ * 42.5 cm³ ≈ 446 g
m≈446 g

Water vapour particles are most likely to phase change into liquid particles if the vapour particle come into contact with A COOLER SURFACE.
For a liquid to change to gas, it has to absorb enough energy to break the chemical bond that is holding the liquid particles together. When a liquid change to gas it is called vaporization. When a vapour, for instance water vapour comes in contact with cooler surfaces they lose energy and get converted back to the liquid state; this process is called condensation.
Using coupons seems like an old-fashioned, time-consuming way to save a few cents on the products you buy at the grocery store.
