Best Answer

If I have Z number of molecules total and 40% of that number is 88 then inorder to find Z I use this.

88 x 100/40 = Z

You would multiply the number of grams x Avogadro's number=number of molecules: (21.6g) X (6.022x10^23)= 1.301x10^25 molecules

A number of atoms/molecules in a given number of moles is regardless of the substance unless it deals with stoicheometry. One mole represents a number of Avogadro's constant, approximately 6.022 x 10^23. Therefore there are 1.91 x 10^25 molecules of water in 31.8 moles.

To get moles given representative particles, simply divide by Avogadro's number: 1.80x1024/6.02x1023 = approx. 3 moles I2.

There is no answerable version of this question, which asks about a certainequation not shown in the question.Further, there is no answerable form of the question. Generally the element that has the largest number of molecules depends on "valence" but all molecules in a given equation could have exactly the same number. There is no way to know.There are already questions that ask about this in answerable forms.

The number of molecules in a given volume of solution depends on the concentration of the solute. Because the concentration is not provided, this question has too little information to answer.

Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules

The state of matter depends on the number of atoms / molecules in a given area / volume. If there are more number of molecules, then it will be in solid state and if it is very less molecules then gases. This inturn may depend on the intermolecular force of attraction between the atoms in them. In the case of solids, the force of attraction is high and hence there are more number of molecules present.

You would multiply the number of grams x Avogadro's number=number of molecules: (21.6g) X (6.022x10^23)= 1.301x10^25 molecules

The given number is 20 (8 divided by 40 then times 100).

The formula for finding the percent is =The given number/Total number *100 Here the given number is 36 . The total number is 150 . Therefore Percent = 36/150*100=24%

When a whole number is given- divide the percent given into the whole number and you will get the original number 39\40 should equal 97.5 great fun you should try it. Works every time.

the X percent of a number is given by x/100 times that number. So. 16 percent of 92 is: 16*92/100

Yes, the less heat there is present, the less heat, the slower the molecules will move. This is due to a lack of energy given from the heat.

No. The state of a substance does not tell the number of molecules present. In a gas, the molecules move more freely than in a liquid as they are not bound to each other by intermolecular forces. If you're going by volume, a given volume of a gas will generally contain fewer molecules except at very high pressures.
