HELP PLEASE... Convert 653 mm Hg to SI units.A. 101,325 PaB. 87,058 PaC. 8700 PaD. 90 kPa

Answer 1

87059.5 Pa

option B

Step-by-step explanation

Let x represent the pressure in Pa

Recall, that 1 mmHg is equivalent to 133.332 Pa

`\begin{gathered} \text{ 1 mmHg ---------> 133.332Pa} \\ \text{ 653 mmHg ------> x Pa} \\ \text{ cross multiply} \\ \text{ 1mmHg }*\text{ x pa = 133.332Pa }*\text{ 653mmHg} \\ \text{ Isolate xPa} \\ \text{ x Pa = }\frac{133.332pa\text{ }*653\cancel{mmHg}}{\cancel{1mmHg}} \\ \text{ x Pa = 133.32 x 653} \\ \text{ x Pa = 87059.5 Pa} \end{gathered}`

Hence, 653mmHg is equivalent to 87059.5 Pa

option B
