How many grams of Cl are in a 38.0-g sample of the chlorofluorocarbon CF2Cl2

1 answer:

4 0

The molecular formula of chlorofluorocarbon is CF₂Cl₂
Molecular mass of CF₂Cl₂ is 120.9 g/mol
Mass of Cl in 1 mol - 2 x 35.5 = 71 g/mol
in 120.9 g of compound - 71 g of Cl
Therefore in 38 g of sample - 71/120.9 x 38 g of Cl
Mass of Cl in 38 g - 22.31 g of Cl

How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?

Crank

Answer:

The answer is " $\bold{6.26 \times 10^{24} \ molecules \ NH_3}\\\\$ "

Explanation:

1-mole molecules as per Avogadro number $= 6.02 \times 10^{23} \ molecules\\\\$

1-mole $NH_3 \to 6.02 \times 10^{23} \ molecules\\\\$

$10.4 \ moles \ of \ \ NH_3 :$

$\to \frac{ 6.02 \times 10^{23} \ molecules }{ 1 \ mole\ NH_3} \times 10.4 \ mole \ NH_3\\\\ \to 6.02 \times 10^{23} \ molecules \times 10.4\\\\\to 62.608 \times 10^{23} \ molecules \\\\\to 6.26 \times 10^{24} \ molecules \ NH_3\\\\$
