If you mean 1.48 x 1024 molecules, just divide by 6.022 x 1023
= 2.46 moles
Find the moles using the formula: moles= grams/molecular mass In this case, molecular mass = 24+4+32 = 60g/mol so 66/60 = 1.1 moles Then, using avogadro's constant, work out the number of molecules. n(molecules) = number of moles x 6.02x10^23 =1.1x 6.02x 10^23 =?
To find the mass of sulfur dioxide (SO₂) that contains the same number of molecules as 2 grams of ammonia (NH₃), you can use the concept of moles and the molar mass. **Find the number of moles of ammonia:** [ \text{Moles of NH₃} = \frac{\text{Mass of NH₃}}{\text{Molar mass of NH₃}} ] The molar mass of ammonia (NH₃) is approximately 17 grams/mol. **Use Avogadro's Number:** According to Avogadro's number, 1 mole of any substance contains the same number of entities (atoms, molecules, etc.), which is approximately (6.022 \times 10^{23}). **Find the number of molecules of ammonia:** [ \text{Number of NH₃ molecules} = \text{Moles of NH₃} \times (6.022 \times 10^{23}) ] **Convert to moles of sulfur dioxide:** Since the number of molecules is the same for both substances, the moles of sulfur dioxide (SO₂) would be the same as the moles of ammonia. [ \text{Moles of SO₂} = \text{Moles of NH₃} ] **Find the mass of sulfur dioxide:** [ \text{Mass of SO₂} = \text{Moles of SO₂} \times \text{Molar mass of SO₂} ] The molar mass of sulfur dioxide (SO₂) is approximately 64 grams/mol. Now, you can substitute the values into the equations to find the mass of sulfur dioxide.
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.
The number of particles (moles, atoms, etc.) can be found using Avogadro's constant, which is displayed as followed: Avogadro's Constant -----> 6.023 x 10^23 To find the number of particles in a certain amount of moles, this constant can be multiplied to your molar value to find your answer. However, if you want to find moles from particles, divide the constant from your value instead of multiplying. The equation looks like this: (7.90 x 10^24) / (6.023 x 10^23) The answer comes out to be approximately 13.116 moles of H2SO4
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
In order to find number of molecules from moles, you must multiply moles by avagadro's number, which is 6.02*10^23.
Molecules can be a very important piece of information while dealing with moles or mass. For example, one can very easily convert molecules to moles to find the mass of a substance (this needs the # of molecules of the compound/element and the chemical formula). Also, the number of molecules can find moles and atoms through different equations.
You first divide the amount of molecules by avagadros number (6.022x10^23) to find out how many moles you have. Then you find out the molecular weight of the compound. You multiply the number of moles by the molecular weight to give you your weight in grams.
To determine the number of molecules in 10.0 g of C8H8O3, we need to calculate the number of moles first. The molar mass of C8H8O3 is 152.15 g/mol. By dividing 10.0 g by the molar mass, we find that there are approximately 0.0658 moles of C8H8O3. To convert moles to molecules, we multiply the number of moles by Avogadro's number, 6.022 x 10^23, giving us about 3.96 x 10^22 molecules.
First we are going to find number of H2 moles form it mass H2 moles=(2.37*10^-4)/2 = 1.185*10^-4moles Since 3 moles of H2 makes 2 moles of NH3 then by using this ration, we can find number of moles in NH3 NH3 moles= (2 * 1.185*10^-4)/3 = 0.79*10^-4 moles Finally, we find number of NH3 molecules by multiplying the number of moles with (6.022*10^23). #NH3 molecules = (0.79*10^-4) *(6.022*10^23) =4.75 * 10^19 molecules of NH3 Good luck Enas

This may not be entirely correct, but here goes. As formula units are the same as molecules but used for ionic compounds whereas molecules are used for covalent, and there are 6.022x10^23 formula units in one mole, it is safe to assume that there are 6.022x10^23 molecules in one mole. So, if you take the number of molecules and divide it by this number, you should be able to find the number of moles. Again, I'm not certain this is correct, but perhaps with some other answers you may be able to find what you're looking for.
The answer is 14,115 moles.
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.
To find moles, simply divide the number of representative particles (in this case, molecules of methane) by Avogadro's number (6.02x1023.)2.45x1023/6.02x1023 = approx. 0.41 moles (the exponents cancel out.)
