Answer:

1.89 g CaCO₃

Explanation:

You will have to use stoichiometry for this question.  First, look at the chemical equation.

Na₂CO₃  +  CaCl₂  ==>  2 NaCl  +  CaCO₃

From the above equation, you can see that for one mole of Na₂CO₃, you will produce one mole of CaCO₃.  This means that however many moles of Na₂CO₃ you have in the beginning, you will have the same amount of moles  of CaCO₃, theoretically speaking.

So, convert grams to moles.  You should get 0.0189 mol Na₂CO₃.  This means that you will get 0.0189 mol CaCO₃.  I'm not sure what units you want the answer in, but I'm going to give it in grams.  Convert moles to grams.  Your answer should be 1.89 g.

Calculate the volumeof 1.0M NaOH necessary to completely neutralize 100mL of 0.50M of phosphoric acid (H3PO4)?
blondinia [14]

Answer:

50 mL

Explanation:

In case of titration , the following formula is used -

M₁V₁ = M₂V₂

where ,

M₁ = concentration of acid ,

V₁ = volume of acid ,

M₂ = concentration of base,

V₂ = volume of base .

from , the question ,

M₁ =  0.50M

V₁ = 100 mL

M₂ =  1.0M

V₂ = ?

Using the above formula , the volume of base , can be calculated as ,

M₁V₁ = M₂V₂

substituting the respective values ,

0.50M * 100 mL =  1.0M * V₂  

V₂  = 50 mL
