Answer : The mass of calcium chloride is, 116.84 grams
Solution : Given,
Molar mass of calcium chloride, [tex]CaCl_2[/tex] = 110.98 g/mole
Number of molecules of calcium chloride = [tex]6.34\times 10^{23}[/tex]
As we know that,
1 mole of calcium chloride contains [tex]6.022\times 10^{23}[/tex] molecules of calcium chloride
or,
1 mole of calcium chloride contains 110.98 grams of calcium chloride
Or, we can say that
As, [tex]6.022\times 10^{23}[/tex] molecules of calcium chloride present in 110.98 grams of calcium chloride
So, [tex]6.34\times 10^{23}[/tex] molecules of calcium chloride present in [tex]\frac{6.34\times 10^{23}}{6.022\times 10^{23}}\times 110.98=116.84grams[/tex] of calcium chloride
Therefore, the mass of calcium chloride is, 116.84 grams
