Answer:

19.7 g of CaCl₂ are produced

Explanation:

This is the reaction:

CaCO₃ + 2HCl →  CaCl₂  +  CO₂  +  H₂O

As we have the mass of reactants, we should determine the moles we used, of each

29g . 1mol / 10.08 g = 0.289 moles

13 g . 1mol / 36.45 g = 0.356 moles

Ratio is 1:2, so If I have 1 mol of carbonate I need the doulbe of hydrochloric. Certainly the limiting reactant is the HCl.

I have 0.289 moles of salt and I need 0.578 (x2) moles of acid. - I only have 0.356 moles.

As we found out the limiting reactant we can work with the reaction. Ratio with CaCl₂ is 2:1 so,

2 moles of HCl produce 1 mol of CaCl₂

Then, 0.356 moles of HCl would produce (0.356 . 1) / 2 = 0.178 moles.

To convert the moles to mass we do: 0.178 mol . 110.98 g / 1mol = 19.7 g

How do you find out mass in science
Aliun [14]
Multiply the volume and density together. Multiply your two numbers together, and you'll know the mass of your object. Keep track of the units as you do this, and you'll see that you end up with units of mass (kilograms or grams). Example: We have a diamond with volume 5,000 cm3 and density 3.52 g/cm3
