Question

Find no. of $H^{+}$ ion present in $H_{2}S{O}_4$.

Answer 1

Number of moles of $H_{2}S{O}_4=\frac{2.34g}{98}$

$=0.023$ moles

Number of molecules of $H_{2}S{O}_4=0.023\times N_A$

$=1.4\times {10}^{22}$ molecules

Each molecule of $H_{2}S{O}_4$ contains $2$ $H$-atoms

Therefore, number of $H^{+}$ ions= $2\times 1.4\times {10}^{22}$

Number of $H^{+}$ ions= $2.8\times {10}^{22}$
