Answer 1

Question#74852 – Chemistry – General chemistry

Question: what mass of c2h5cl can be produced from 25.00g of Cl₂

Solution:

1. An equation of the reaction:

$$\mathrm{C_2H_6} + \mathrm{Cl_2} \xrightarrow{\mathrm{h^0}} \mathrm{C_2H_5Cl} + \mathrm{HCl}$$

2. Find moles of $\mathrm{C_2H_5Cl}$:

$$n(\mathrm{C_2H_5Cl}) = n(\mathrm{Cl_2}) = \frac{m(\mathrm{Cl_2})}{M(\mathrm{Cl_2})} = \frac{25.00\ \mathrm{g}}{70.91\ \frac{\mathrm{g}}{\mathrm{mol}}} = 0.3526\ \mathrm{mol}$$

3. Find the mass of $\mathrm{C_2H_5Cl}$:

$$m(\mathrm{C_2H_5Cl}) = n(\mathrm{C_2H_5Cl}) \times M(\mathrm{C_2H_5Cl}) = 0.3526\ \mathrm{mol} \times 64.51\ \frac{\mathrm{g}}{\mathrm{mol}} = 22.74\ \mathrm{g}$$

Answer: $22.74\ \mathrm{g}\ \mathrm{C_2H_5Cl}$
