What amount of moles does 60.5 L of carbon dioxide occupy at 2.15 atm and 25 degrees C?

xeze [42]

Answer: 5.3 moles

Explanation:

Hi, to answer this question we have to apply the next formula:

n = PV/RT

Where:

n = number of moles

P= Pressure = 2.15 atm

V= volume = 60.5 L

R = 0.0821 atm(L)/mol(K)

T = temperature = 25 °+ 273.15 = 298.15 Kelvin

Replacing with the values given:

n = 2.15 (60.5) / 0.0821 (298.15) = 5.3 moles.

Mars2501 [29]

Answer:

Some beverages or food that contain no sweet taste or less sweet taste, it does not mean that they have negative test for glucose.

Explanations:

Sweetness is being feel, when it interact with taste bed ( tastes organ on tongue).
Sucrose is consider as a standard sweetener having rating 1.
While is almost sweetener but its rating is 0.7 only that's why some time we don't feel sweetness after using such a food that contain glucose.

Conclusion:

Actually, the metabolic component are breakdown into simpler carbohydrates like sugar, fructose that become source of energy in blood stream. These sugar like glucose are less sweet than sucrose. So we sometimes don't feel sweetness.
