Answer:
65.25 grams of water
Explanation:
Moles of H2 = mass/ M.w
= 7.25g /2
=3.625 mol H2
Moles of H2O = moles of H2 = 3.625 mole
Mass of H2O = mol * molar wight
= 3.625 * 18 = 65.25 g H2O
Liquid 2 because the lower the density the more it floats and the higher the density the more it sinks. The order from top to bottom is liquid 2, liquid 3, liquid 1
