Given a barometric pressure of 762.4 mmHg, what is the pressure in atmospheres (atm)?
A
1.01 atm
B
0.98 atm
C
1.00 atm
D
1.03 atm
Verified step by step guidance1
Understand the relationship between mmHg and atm: 1 atm is equivalent to 760 mmHg.
Set up the conversion factor: Since 1 atm = 760 mmHg, you can use this ratio to convert mmHg to atm.
Write the conversion equation: \( \text{Pressure in atm} = \frac{\text{Pressure in mmHg}}{760} \).
Substitute the given pressure into the equation: \( \text{Pressure in atm} = \frac{762.4}{760} \).
Perform the division to find the pressure in atm, ensuring to keep track of significant figures based on the given data.
