One container of tums® costs 4.00 dollars. each container has eighty 1.00 g tablets. assume each tums® is 40.0 percent caco₃ by mass. using only tums®, you are required to neutralize 0.500 l of 0.400 m hcl. how much does this cost? assume you are able to purchase individual tablets. express your answer in dollars.

The total cost is 1.25 dollars.

Step-by-step explanation:      

The reaction between HCl and CaCO₃ is giving by:

2HCl(aq) + CaCO₃(s)   →   CaCl₂(aq) + CO₂(g) + H₂O(l) (1)

0.500L     M: 100.01g/mol        

0.400M

According to equation (1), 2 moles of HCl react with 1 mol of CaCO₃, so to neutralize HCl, we need the next amount of CaCO₃:

The CaCO₃ mass of each tablet is:

Hence, the number of tablets that we need to neutralize the HCl is:

Finally, if every 80 tablets costs 4.00 dollars, 25 tablets will cost:

So, the total cost to neutralize the HCl is 1.25 dollars.

I hope it helps you!

a² + b²= c²

24² + 7² = c²
