Answer: 64.6 mmHg

Explanation:

Given that:

Volume of gas V = 3.47L

(since 1 liter = 1dm3

3.47L = 3.47dm3)

Temperature T = 85.0°C

Convert Celsius to Kelvin

(85.0°C + 273 = 358K)

Pressure P = ?

Number of moles of gas N = 0.100 mole

Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

p x 3.47dm3 = 0.10 x (0.0082 atm dm3 K-1 mol-1 x 358K)

p x 3.47dm3 = 0.29 atm dm3

p = (0.29 atm dm3 / 3.47 dm3)

p = 0.085 atm

Recall that pressure of the gas is required in mm hg, so convert 0.085 atm to mm Hg

If 1 atm = 760 mm Hg

0.085atm = 0.085 x 760

= 64.6 mm Hg

Thus, the pressure of the gas is 64.6 mm hg

An 8 oz serving of whole milk has 8.0 g of fat, 8.0 g of protein, and 13 g of carbohydrates. Approximately how many kilocalories
dsp73
<h3>Answer:</h3>

156 calories

<h3>Explanation:</h3>
  • Carbohydrates, proteins and fats are food substances used by living organisms to generate energy required for the day to day activities.
  • They supply energy which differs per gram for each food substance.
  • That is;

1 g of carbohydrate = 4 calories

1 g of fat = 9 calories

1 g of protein = 4 calories

Therefore, whole milk serving containing 8.0 g of fat, 8.0 g of protein and 13 g of carbohydrates will contain the following number of calories;

8.0 g of fat = 8 g × 9 cal/g = 72 calories

8.0 g of protein = 8 g × 4 cal/g = 32 calories

13 g of carbohydrates = 13 g × 4 cal/g = 52 calories

Total amount of energy = 156 calories

Therefore, an 8 oz serving of whole milk contains 156 calories

In which situation is no work considered to be done by a force?
Elena L [17]
Work is done when the application of a force causes movement of an object in the direction of the force.
If there is no movement of the object or the object does not move in the direction of the force then work is not done.

How does the average temperature change as the latitude decreases from the poles to the equator
Lorico [155]

The hottest temperatures are found in the lower latitude areas while the coldest are found in the highest. Basically the closer the sun is the hotter the area is and the farther away the sun is the colder it is.
