24 grams C convert to moles

Anon25 [30]

Answer:

Number of moles = 2 mol

Explanation:

Given data:

Mass of carbon = 24 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of carbon is 12 g/mol.

Now we will put the values in formula.

Number of moles = 24 g/ 12 g/mol

Number of moles = 2 mol

Which explanation best compares the movement of particles in the three states of matter?

Degger [83]

The correct answer is the second statement. Particles in a solid can only vibrate. In a liquid, they slide against each other. In a gas, they move freely, bouncing and bumping into each other. Solids are packed thus molecules are restricted and can only vibrate. Liquids, on the other hand, molecules can move and slide against each other since they are loosely packed. Lastly, gas particles is very loosely packed so they can move freely.

What are the three particles of an atom?

Dmitry [639]

The three particles found in an atom are the protons, neutrons and electrons. Protons have a positive charge. Electrons have negative charge. Lastly, neutrons have no net electrical charge. Protons and neutrons are much heavier than electrons and are located in the center of the atom.

The vapor pressure of ethanol is 54.68 mm Hg at 25°C. How many grams of estrogen (estradiol), C18H24O2, a nonvolatile, nonelectr

amm1812

Answer:

30.5 g of estrogen

Explanation:

Lowering vapor pressure formula → P° - P' = P° . Xm

P° → Vapor pressure of pure solvent → 54.68 mmHg

P' → Vapor pressure of solution → 53.46 mmHg

54.68 mmHg - 53.46 mmHg = 54.68 mmHg . Xm

0.0223 = Xm → This is the mole fraction for solute

Moles of solute / Total moles

Total moles = Moles of solute + Moles of solvent

Let's determine the moles of solvent → 228 g / 46.07 g/mol = 4.95 moles

Let's determine the moles of solute

Moles of solute / Moles of solute + 4.95 = 0.0223

Moles of solute = 0.0223 . Moles of solute + 0.110

0.9777 moles of solute = 0.110

Moles of solute = 0.110 / 0.9777 → 0.112

Now we can convert the moles to mass to finish the excersise:

0.112 mol . 272.4 g/mol = 30.5 g
