Pb(OH)Cl, one of the lead compounds used in ancient Egyptian cosmetics, was prepared from PbO according to the following recipe:
sladkih [1.3K]

Answer:

8.59 g

2.25 g

Explanation:

According to the given situation the calculation of grams of PbO and grams of NaCL is shown below:-

Moles of Pb(OH)CL is

= \frac{Mass}{Molar\ mass}

= \frac{10.0 g}{259.65g / mol}

= 0.0385 mol

Mass of PbO needed is

= 0.385mol Pb(OH) Cl\times \frac{1 mol PbO}{1molpb (OH) cl} \times \frac{223.2g PbO}{1mol PbO}

After solving the above equation we will get

= 8.59 g

Mass of NaCL needed is

= \frac{1mol\ NaCl}{1molPb\ (OH)Cl} \times \frac{58.45NaCl}{1mol NaCl}

After solving the above equation we will get

= 2.25 g

Therefore we have applied the above formula.
