A sample containing only CaCo_(3) and MgCo_(3) is ignited to CaO and MgO. The mixture of oxides produced weight exactly half as much as the original sample. Calculate the percentages of CaCO_(3) and MgCO_(3) (by mass) in the sample.

1.84 g of CaCO_3 and MgCO_3 were treated with 50 mL of 0.8 HCl solution. Calculate the percentage of CaCO_3 and MgCO_3 .

1.84 g of CaCO_3 and MgCO_3 were treated with 50 mL of 0.8 HCl solution. Calculate the percentage of CaCO_3 and MgCO_3 .

10 grams of a mixture of CaCO_(3) and MgCO_(3) require equal weight of sulphuric acid for complete reaction. Calculate the percentage weight of MgCO(3) in the mixture.

"2.6 g of CaCO"_(3) and MgCO_(3) mixture is heated to a constant weight of 1.3 g. The mass of CaCO_(3) in mixture is :

A 0.6gm sample consisting of only CaC_(2)O_(4) and MgC_(2)O_(4) is heated at 500^(@)C gets converted into CaCO_(3) and MgCO_(3) . The sample then weighed 0.465gm. If the sample had been heated to 900^(@)C where the products are CaO and MgO, then what would the mixture of oxides weigh?
