Answer
(i) $2.25 \times 10^7 \space Pa$
(ii) $225 \space bar$
Work Step by Step
1. Identify the conversion factors:
You can find these values on Table A.1, in the Resource Section.
atm-pascal: $1 \space atm = 101.325 \space kPa$
pascal-bar: $10^{5} \space Pa = 1 \space bar$
kilo($k$) = $10^3$
2. Convert 222 atm into pascal:
$$222 \space atm \times \frac{101.325 \space kPa}{1 \space atm} = 2.25 \times 10^4 \space kPa$$ $$2.25 \times 10^4 (10^3) \space Pa = 2.25 \times 10^7 \space Pa$$
3. Calculate the same value in bar:
$$2.25 \times 10^7 \space Pa \times \frac{1 \space bar}{10^5 \space Pa} = 225 \space bar$$
