Answer : The theoretical yield of water in this reaction is 360 g.

Solution : Given,

Mass of LiOH=1\times 10^3g=1000g

Mass of CO_2=8.80\times 10^2g=880g

Mass of H_2O=3.25\times 10^2g=325g

Molar mass of CO_2 = 44 g/mole

Molar mass of LiOH = 24 g/mole

Molar mass of H_2O = 18 g/mole

First we have to calculate the moles of CO_2 and LiOH.

Moles of CO_2 = \frac{\text{ Mass of }CO_2}{\text{ Molar mass of }CO_2}= \frac{880g}{44g/mole}=20moles

Moles of LiOH = \frac{\text{ Mass of }LiOH}{\text{ Molar mass of }LiOH}= \frac{1000g}{24g/mole}=42moles

The given balanced chemical reaction is,

CO_2+2LiOH\rightarrow Li_2CO_3+H_2O

From the given reaction, we conclude that

1 mole of CO_2 react with 2 mole of LiOH

20 moles of CO_2 requires 20\times2=40moles of LiOH

But the actual moles of LiOH = 42 moles

Excess moles of LiOH = 42 - 40 = 2 moles

So, CO_2 is the limiting reagent.

Now we have to calculate the mass of H_2O.

From the reaction, we conclude that

1 mole of CO_2 gives 1 mole of H_2O

20 moles of CO_2 gives 20 moles of H_2O

Mass of H_2O = Moles of H_2O × Molar mass of  H_2O

Mass of H_2O = 20 moles × 18 g/mole = 360 g

The experimental yield of H_2O = 325 g

Therefore, the theoretical yield of H_2O = 360 g

Does anyone know how to do this? the solubility of barium carbonate, BaCO3, is 0.0100 g/L. Its molar mass is 197.3 g/mol. What i
g100num [7]
It's simple, just follow my steps.

1º - in 1 L we have 0.0100~g of BaCO_3

2º - let's find the number of moles.

\eta=\frac{m}{MM}

\eta=\frac{0.0100}{197.3}

\boxed{\boxed{\eta=5.07\times10^{-5}~mol}}

3º - The concentration will be

C=5.07\times10^{-5}~mol/L

But we have this reaction

BaCO_3\rightleftharpoons Ba^{2+}+CO_3^{2-}

This concentration will be the concentration of Ba^{2+}~~and~~CO_3^{2-}

K_{sp}=\frac{[Ba^{2+}][CO_3^{2-}]}{[BaCO_3]}

considering [BaCO_3]=1~mol/L

K_{sp}=[Ba^{2+}][CO_3^{2-}]

and

[Ba^{2+}]=[CO_3^{2-}]=5.07\times10^{-5}~mol/L

We can replace it

K_{sp}=(5.07\times10^{-5})*(5.07\times10^{-5})

K_{sp}\approx25.70\times10^{-10}

Therefore the K_{sp} is:

\boxed{\boxed{\boxed{K_{sp}\approx2.57\times10^{-11}}}}
