A 5.00-L tank contains helium gas at 1.50 atm. What is the pressure of the gas in mmHg?
A
1013 mmHg
B
760 mmHg
C
1140 mmHg
D
1130 mmHg
Verified step by step guidance1
Identify the given pressure in atm and the desired pressure unit, which is mmHg.
Recall the conversion factor between atm and mmHg: 1 atm = 760 mmHg.
Set up the conversion equation to convert pressure from atm to mmHg: \(P_{mmHg} = P_{atm} \times 760\).
Substitute the given pressure value into the equation: \(P_{mmHg} = 1.50 \times 760\).
Perform the multiplication to find the pressure in mmHg (do not calculate the final value here, just set up the expression).
