Answer
a. $$ 0.832 \space atm$$
b. $$ 632 \space mmHg$$
c. $$ 12.2 \space psi$$
d.$$ 8.43 \times 10^{4} \space Pa$$
Work Step by Step
a. $$ 24.9 \space in Hg \times \frac{1 \space atm}{29.92 \space in Hg} = 0.832 \space atm$$
b. $$ 24.9 \space in Hg \times \frac{1 \space atm}{29.92 \space in Hg} \times \frac{760 \space mmHg}{1 \space atm} = 632 \space mmHg$$
c. $$ 24.9 \space in Hg \times \frac{1 \space atm}{29.92 \space in Hg} \times \frac{14.7 \space psi}{1 \space atm} = 12.2 \space psi$$
d.$$ 24.9 \space in Hg \times \frac{1 \space atm}{29.92 \space in Hg} \times \frac{101325 \space Pa}{1 \space atm} = 8.43 \times 10^{4} \space Pa$$
