Gas stoichiometry and Percentage of calcium carbonate in the sample
At a certain temperature, a volume of 100 mL of saturated barium carbonate solution contains 0.00216 g of BaCO3 (MW=197.3 g/mol).
the gas sample weighs 2.62grams then computes the molecular weight and determines the identity of the gas.
A 50.0-L stainless steel container was charged with 3.00 atm of hydrogen gas and 4.00 atm of oxygen gas. A spark ignited the mixture, producing water.
Determine the concentration of the sodium hydroxide solution? Considering this balanced equation given as :
