A can of coke contains 25 mL of carbon dioxide gas at 100kPa. If you take it on a hike up Mount Everest and the pressure decreas
Mazyrski [523]

Answer:

50 mL

Explanation:

We can solve this problem by using Boyle's Law, which states that:

"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

p\propto \frac{1}{V}

where

p is the pressure of the gas

V is the volume of the gas

The equation can be rewritten as

p_1 V_1 = p_2 V_2

where in this problem:

p_1 = 100 kPa is the initial pressure of the gas in the coke

V_1=25 mL is the initial volume

p_2=50 kPa is the final pressure

Solving for V2, we find the final volume:

V_2=\frac{p_1 V_1}{p_2}=\frac{(100)(25)}{50}=50 mL

a soft drink contains 47.0 carbohydrates per serving. calculate the number of nutritional calories (cal) per serving in this dri
Zolol [24]

A soft drink that contains 47 grams of carbohydrates per serving has a nutritional calories (cal) per serving of 188 calories.

Calories are a measurement of energy released from your body after digestion and absorption of food whereas carbohydrate is a carbon-based organic compound consisting of carbon, hydrogen, and oxygen atoms with a general chemical molecular formula of CH₂O.

In order to get the number of nutritional calories per serving from a soft drink that has 47 grams of carbohydrate, we will need to multiply the number of grams by 4 since there are about 4 calories for every gram of carbohydrate, and the calculation is as follows:

47×4=188

Hence, there are 188 calories in a soft drink that contains 47 grams of carbohydrates.
