What is the molarity of the solution with respect to NaCL

Chemistry
1 answer:
dezoksy [38]3 years ago
6 0
7.0 g in 220 ml corresponds to 7 x 1000/220 = 31.818g per 1000 cc of solution or 1 liter of solution

Molarity is moles per liter of solution by definition, so we need to know the number of moles of NaCl in 31.818 grams. The molar mass of NaCl is 58.5 grams(rounded off), so # moles = 31.818/58.5 = 0.543. 0.543 moles in a liter of solution defines the concentration as 0.543M

Calculate the mass of calcium chloride that contains 3.20 x 1024 atoms of chlorine.
frez [133]

Answer:

294.87 gm  CaCl_2

Explanation:

The computation of the  mass of calcium chloride is shown below:

But before that following calculations need to be done

Number of moles of chlorine atom is

= 3.20 × 10^24 ÷ 6.022 × 10^23

= 5.314 moles

As we know that

1 mole CaCl_2 have the 2 moles of chlorine atoms

Now 5.341 mole chloride atoms would be

= 1 ÷ 2 × 5.314

= 2.657 moles

Now

Mass of CaCl_2 = Number of moles × molar mass of  CaCl_2

= 2.657 moles × 110.98 g/mol

= 294.87 gm  CaCl_2
