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

AysviL [449]

Answer:

B) 1.65

Explanation:

See the image uploaded for the percent error formula

Work:

Theoretical Value - Accepted Value/Accepted Value * 100

= (24.7-24.3)/24.3 * 100

= 0.4/24.3 * 100

= 0.0164609053 * 100

= 1.64609053

Can be rounded to 1.65%
