The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO
Nataly [62]
The reaction that results from this is:

H2O + CO2 --> H2CO3

Stoichiometric ratio between water and CO2 is 1:1. So we can say that for every Mole of CO2, we need 1 Mole of water to produce 1 Mole of H2CO3. Thus as n=m/M we can find n = 528/44.01 = 11.997 ~ 12Mol.

therefore, we need 12 moles of water.

Which of the following reasons (specific to this lab) would have caused the percent yield of calcium carbonate to be less than 1
mote1985 [20]

Answer:

Some of the calcium carbonate remained stuck to the side of the glassware after filtering

Some of the calcium carbonate spilled when measuring its mass

Explanation:

The percent yield is obtained from;

Actual yield/Theoretical yield * 100

Usually, the actual yield is less than the theoretical yield thereby making the percent yield less than 100%.

In the case of this particular reaction; when some calcium carbonate remains stuck on the glassware or some calcium carbonate is spilled during weighing, the actual yield of product obtained from the reaction becomes less than the theoretical or calculated yield hence the percent yield becomes less than 100%.
