2 How many pascals (Pa) are in 850 torr? 101,325Pa 96,500Pa 7500Pa 113,324Pa Clear my selection Multiple Choice 1 point If agas pressure is 50 mm Hg, what is the pressure in atmospheres (atm)? 0.060 atm 0.5 atm 0.0658 atm 0.085 atm Clear my selection

1. To convert torr to pascals, we can use the conversion factor: 1 torr = 133.322 pascals.<br /><br />Given that the pressure is 850 torr, we can calculate the pressure in pascals as follows:<br /><br />\[ 850 \, \text{torr} \times 133.322 \, \text{Pa/torr} = 113,324 \, \text{Pa} \]<br /><br />Therefore, the correct answer is $113,324 \, \text{Pa}$.<br /><br />2. To convert mm Hg to atmospheres, we can use the conversion factor: 1 mm Hg = 0.133322 atmospheres.<br /><br />Given that the pressure is 50 mm Hg, we can calculate the pressure in atmospheres as follows:<br /><br />\[ 50 \, \text{mm Hg} \times 0.133322 \, \text{atm/mm Hg} = 0.066661 \, \text{atm} \]<br /><br />Therefore, the correct answer is $0.0658 \, \text{atm}$.
