What is kinetic energy of 1 g of 

{\mathrm{O}_2}{\mkern 1mu} {\mkern 1mu} \mathrm{at}{\mkern 1mu} {\mkern 1mu} 47\,\,^\circ C?

View answer and explanation

Correct option: A

1.24 \times {10^2}\mathrm{J}

Option A (

1.24 \times {10^2}\mathrm{J}

) is correct because it uses the formula for kinetic energy based on temperature and the number of moles of oxygen.
