ANSWER
87059.5 Pa
option B
EXPLANATION
Let x represent the pressure in Pa
Recall, that 1 mmHg is equivalent to 133.332 Pa
[tex]\begin{gathered} \text{ 1 mmHg ---------> 133.332Pa} \\ \text{ 653 mmHg ------> x Pa} \\ \text{ cross multiply} \\ \text{ 1mmHg }\times\text{ x pa = 133.332Pa }\times\text{ 653mmHg} \\ \text{ Isolate xPa} \\ \text{ x Pa = }\frac{133.332pa\text{ }\times653\cancel{mmHg}}{\cancel{1mmHg}} \\ \text{ x Pa = 133.32 x 653} \\ \text{ x Pa = 87059.5 Pa} \end{gathered}[/tex]Hence, 653mmHg is equivalent to 87059.5 Pa
