A sample contained a mixture of MgCO 3 and BaCO 3. The amount of MgCO 3 was determined by reacting 9.473 g of the sample with an excess of HCl to release CO 2 from each compound; MgCO 3(s) + 2 HCl(aq) → MgCl 2 + CO 2(g) BaCO 3(s) + 2 HCl(aq) → BaCl 2 + CO 2(g) If the sample reacted completely and produced 2313 mL of carbon dioxide at 27.70 °C and 685.6 mm Hg, what was the mass percentage of MgCO 3 in the mixture?

I've tried attempting this problem about 3 times now and each time on the attempts of my homework I've gotten it wrong. Can I get any help with it?
A sample contained a mixture of MgCO 3 and BaCO 3. The amount of MgCO 3 was determined by reacting 9.473 g of the sample with an excess of HCl to release CO 2 from each compound;
MgCO 3(s) + 2 HCl(aq) → MgCl 2 + CO 2(g)
BaCO 3(s) + 2 HCl(aq) → BaCl 2 + CO 2(g)
If the sample reacted completely and produced 2313 mL of carbon dioxide at 27.70 °C and 685.6 mm Hg, what was the mass percentage of MgCO 3 in the mixture?
