The chemical acidity of a solution is measured in units of pH: $\mathrm { pH } = - \log \left[ \mathrm { H } ^ { + } \right]$ ,where $\left[ \mathrm { H } ^ { + } \right]$ is the hydrogen ion concentration in the solution.If a sample of rain has a pH of 3.3,how many times higher is its $\left[ \mathrm { H } ^ { + } \right]$ than pure water's,which has a pH of 7?
A) $5.0 \times 10 ^ { 4 }$
B) $2.0 \times 10 ^ { 4 }$
C) $2.0 \times 10 ^ { 3 }$
D) $5.0 \times 10 ^ { 3 }$
E)7
