pA manometer is connected to a gas containing bulb. The open arm reads \( 53.3 \mathrm{~cm} \), whereas the arm connected to the bulb reads \( 15.6 \mathrm{~cm} \). If the barometric pressure is \( 763 \mathrm{~mm} \) mercury, then what is the pressure of gas in atm?/pp(a) \( 1.05 \mathrm{~atm} \)/pp(b) \( 1.5 \mathrm{~atm} \)/pp(c) \( 0.51 \mathrm{~atm} \)/pp(d) \( 1.91 \mathrm{~atm} \)/p
