One container of tumsr costs 4.00 dollars. each container has eighty 1.00 g tablets. assume each tumsr is 40.0 percent caco₃ by mass. using only tumsr, 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.

1.25 dollars.

Explanation:

The balanced reaction will be

mole ratio of and HCl is 1 : 2

mole of HCl will be as

0.500 L HCl × 0.4 mol/L = 0.2 mol HCl

moles of will be as

0.2 mole HCl × 1 mol mol HCl = 0.1 mol

mass of will be calculated as :

0.1 mol × 100.1 g / 1 mol = 10.01 g

Now 40.0% = = 0.4

mass of / (80 tablets × 1 g /tablets × 0.4 = number of containers

= 0.3128125 (number of containers)

Cost = number of containers × $4.00

        = 0.3128125 × 4.00

       =  $1.25

Cost would be $1.25.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
