- Mass→Mass & Mass→Vol : Zinc citrate is used in toothpaste it is synthesized from zinc carbonate and citric acid according to the following reaction. A) What mass of Zn₃(C₆H₅O₇)₂ can be produced from 2240. g of ZnCO₃? B) How many L of CO₂ will be produced at STP by this amount? 3ZnCO3(s)+2C6H8O7(aq)--->Zn3(C6H5O7)2+3H2O(1)+3CO2(g)arrow_forwardWhat volume of hydrogen gas (in mL) at 703 mm Hg and 40 °C can be produced when 2.9 g of MgCO3(s) are put into an Erlenmeyer flask containing 130 mL of 0.137 M HCl(aq) ?1 MgCO3(s) + 2 HCl(aq) → MgCl2(aq) + CO2(g) + H2O(l)arrow_forwardPart A. Multiple Choice Identify the choice that best completes the statement or answers the question. L·atm R = 0.08206 mol · K 1. At 0.982 atm, the height of mercury in a barometer is 0.746 m. If the mercury were replaced with ethanol, what height of ethanol (in meters) would be supported at this pressure? The densities of Hg and ethanol are 13.5 g/cm³ and 0.789 g/cm³, respectively. а. 0.0436 m b. 0.946 m с. 0.760 m d. 12.8 m е. 13.0 marrow_forward
