NEED HEL
Betty while doing an underwater experiment is tasked with determining the buoyancy of a research balloon at test depth. The balloon is initially inflated with 40.0 L of air at sea level (1.00 atm and 25.0⁰C) and sinks in the water to where the pressure is 11.0 atm and 4.0⁰C. She used the combined gas law to calculate that the final volume will be 3.38 L of air.

The following reaction shows sodium carbonate reacting with calcium hydroxide. na2co3 + ca(oh)2 → naoh + caco3 how many grams of naoh are produced from 20.0 grams of na2co3? (molar mass of na = 22.989 g/mol, c = 12.01 g/mol, o = 15.999 g/mol, ca = 40.078 g/mol, h = 1.008 g/mol) 12.2 grams 15.1 grams 24.4 grams 30.2 grams
