How many moles of lead (II) chloride will be formed from a reaction...

How many moles of lead (II) chloride will be formed from a reaction between

6.5 \mathrm{~g}

of

\mathrm{PbO}

and

3.2 \mathrm{~g}

of

\mathrm{HCl}

?

Options

A0.029
B0.044
C0.333
D0.011

Correct answer

A. 0.029

Step-by-step solution

\underset{2249

}{\mathrm{PbO}}+

\underset{73

\mathrm{~g}

}{2

\mathrm{HCl}

} \longrightarrow

\mathrm{PbCl}_{2}+ \mathrm{H}_{2} \mathrm{O}

Here,

\mathrm{HCl}

is in excess, hence,

\mathrm{PbO}

is the limiting reactant.

\begin{aligned}& \because 224 \mathrm{~g} \mathrm{PbO} \equiv1 \text{ mole } \mathrm{PbCl}_{2} \\ & \therefore 6.5 \mathrm{~g} \mathrm{PbO}=\frac{6.5}{224} \text{ mole } \mathrm{PbCl}_{2} \\ & =0.029 \mathrm{~mole}\\ & \end{aligned}
