I really need help with this question for my chem H.W.
1) On a summer day in Breckenridge, Colorado, the atmospheric pressure is 525 mm Hg. What is this air pressure in atmospheres?
(round to the hundredths place) atm
1 atm = 760 mm Hg
Therefore 525 mm Hg = 525/760 = 0.69 atm
Why did the chemistry book go to therapy? Because it had too many mole-cules!
Now, let's get down to business – to convert mm Hg to atmospheres, we can use the conversion factor of 1 atm = 760 mm Hg.
So, to convert 525 mm Hg to atmospheres, we divide 525 by 760.
Calculating this, we get approximately 0.69 atm (rounded to the hundredths place).
So, the air pressure in Breckenridge, Colorado, on that summer day would be approximately 0.69 atm.
To convert atmospheric pressure from mm Hg to atmospheres (atm), you can use the conversion factor:
1 atm = 760 mm Hg.
Given the atmospheric pressure in Breckenridge, Colorado is 525 mm Hg, you can calculate the pressure in atmospheres by dividing 525 mm Hg by 760 mm Hg:
525 mm Hg / 760 mm Hg = 0.6908 atm.
Therefore, the air pressure in Breckenridge, Colorado is approximately 0.69 atm (rounded to the hundredths place).
To convert the pressure from units of mm Hg (millimeters of mercury) to atmospheres, you can use the conversion factor that 1 atm is equal to 760 mm Hg. Here's how you can solve this problem step-by-step:
1. Write down the given information:
- Atmospheric pressure in Breckenridge, Colorado: 525 mm Hg.
2. Set up the conversion factor:
- 1 atm = 760 mm Hg.
3. Plan your calculation:
- You can use a proportion to solve for the pressure in atmospheres.
4. Solve the proportion:
- Set up the following proportion: 525 mm Hg / 1 atm = x mm Hg / 760 mm Hg.
- Cross-multiply: 525 mm Hg * 760 mm Hg = x mm Hg * 1 atm.
- Simplify: 399,000 mm Hg = x mm Hg * 1 atm.
5. Solve for x:
- Divide both sides of the equation by 760 mm Hg to isolate x: 399,000 mm Hg / 760 mm Hg = x.
- Calculate: x ≈ 525 mm Hg / 760 mm Hg.
- The pressure in atmospheres is approximately x = 0.69 atm (rounded to the hundredths place).
So, the air pressure in Breckenridge, Colorado, on that summer day is approximately 0.69 atm.
