NEET Physics MCQ: NCERT Unit Conversion

A chemist measures a reaction rate as $2.5 imes 10^{-3}$ mol L $^{-1}$ $s^{-1}$ . Express this rate in molecules $cm^{-3}$ $\mu s^{-1}$ (molecules per cubic centimeter per microsecond). Avogadro's number = $6.022 imes 10^{23}$ molecules/mol.

$1.5 imes 10^{12}$ molecules $cm^{-3}$ $\mu s^{-1}$

$2.5 imes 10^{18}$ molecules $cm^{-3}$ $\mu s^{-1}$

$1.5 imes 10^{15}$ molecules $cm^{-3}$ $\mu s^{-1}$

$4.2 imes 10^{20}$ molecules $cm^{-3}$ $\mu s^{-1}$
