## 2. How much "Ca" is consumed when "56.8 mL O"_2" reacts with calcium ...

• This reaction will consume 0.201 g of calcium. Explanation: Start by taking a look at the balanced chemical equation for this reaction. 2Ca(s)+O2(g)→2CaO(s).

• This reaction will consume 0.201 g of calcium. Start by taking a look at the balanced chemical equation for this reaction color(red)(2)Ca_((s)) + O_(2(g)) -> 2CaO_((s)) Notice that you have a color(red)(2):1 mole ratio between calcium and oxygen. This means that, regardless of how many moles of oxygen reacted, the reaction needed twice as many moles of calcium. Since you're at STP conditions, you can use the molar volume of a gas at STP. More specifically, you know that at STP conditions, which imply a pressure of 100 kPa and a temperature of 273.15 K, 1 mole of any ideal gas occupies exactly 22.7 L. This means that you can determine how many moles of oxygen reacted by using its volume 56.8cancel("mL") * (1cancel("L"))/(1000cancel("mL")) * "1 mole"/(22.7cancel("L")) = "0.002502 moles" O_2 This means that the reaction also consumed 0.002502cancel("moles"O_2) * (color(red)(2)"moles Ca")/(1cancel("mole"O_2)) = "0.005004 moles" Ca To get the mass of calcium that contained this many moles, use calcium's molar mass 0.005004cancel("moles") * "40.078 g"/(1cancel("mole")) = "0.2006 g" Ca Rounded to three sig figs, the number of sig figs you gave for the volume of oxygen, the answer will be m_(Ca) = color(green)("0.201 g") SIDE NOTE Many textbooks and online sources still list STP conditions as a pressure of 1 atm and temperature of 273.15, which would make the molar volume of a gas equal to 22.4 L, not 22.7 L. If this is the value you're supposed to use, simply redo all the calculations using 22.4 L instead of 22.7 L. The answer should come out to be 0.203 g of calcium.
