A drop of solution of volume

0.05\,\text{mL}

contains

3.0\times10^{-6}\,\text{mol}

\mathrm{H^+}

. If the rate constant for disappearance of

\mathrm{H^+}

1.0\times10^7\,\text{mol L}^{-1}\text{s}^{-1}

, how long would it take for the

\mathrm{H^+}

in the drop to disappear? (a)

6\times10^{-8}\,\text{s}

(b)

6\times10^{-7}\,\text{s}

(c)

6\times10^{-9}\,\text{s}

(d)

6\times10^{-10}\,\text{s}
