A glass cylinder contains four liquid layers: mercury (d = 13.6 g/mL), chloroform (d = 1.49 g/mL), water (d = 1.00 g/mL) and ether (d = 0.708 g/mL). If a solid ball (d = 1.45 g/mL) is dropped into the cylinder, where does it come to rest?

The decomposition of methane, CH4, the main component of natural gas can be used to generate hydrogen fuel. The decomposition gives carbon (C) and hydrogen (H) in a ratio of 3.00 parts by mass of carbon to 1.00 part by mass of hydrogen. How much hydrogen can be made from 62.0 g methane?
