120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH. Each mole of any substance contain Avogadro's number of molecules ie., 6.022 x (10 to the power 23).

The number of particles is present in One mole equals to Avogadro number. So, the number of glucose molecules in one mole is 6.022 * 10^23.

So one molecule contains a total of three atoms. Next, find you how many molecules of hydrogen sulfide you get in that many moles. You know that one mole of a substance contains exactly 6.022⋅1023 molecules of that substance - this is known as Avogadro's number.

In order to have one mole of a molecular substance, you need to have 6.022⋅1023 molecules of that substance → this is known as Avogadro's number and it can be used as a conversion factor to go from number of molecules to moles and vice versa.

Avogadro's number tells us there are 6.022 x 1023 molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles: molecules in a drop of water = (6.022 x 1023 molecules/mole) x 0.002275 moles.

Popular Answers (1) of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.

Avogadro's number tells us that there are 6.022 x 10^23 molecules of water per mole of water. So, next, we calculate how many molecules there are in a drop of water, which we determined: molecules in a water drop = (6.022 x 102^3 molecules/mole) x 0.002275 moles.

If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

Each mole is 6.02214179 * 10^23 molecules. So we have 1.670829 *10^21 molecules. Each molecule of water has three atoms (two hydrogen, one oxygen). So we have 5.0124896 *10^21 atoms in one drop of water.

Since 1 molecule contains 1 atom each of Na and Cl, 1 mole of NaCl will contain 1 mole each of Na and Cl. We know that 1 mole of anything contains an Avogadro's number of atoms or 6.023 x 10^23 atoms. Thus, 1 mole of NaCl will contain 6.023 x 10^23 atoms each of Na and Cl, or a total of 12.046 x 10^23 atoms.

There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole. To calculate for 5 moles, (2 H atom)/(H2O molecule) X (6.022x10^23 H2O molecules)/(mole) X 5 moles = 6.022x10^24.

But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).

Therefore 2 moles will have 1.204*10^24 molecules of NH3. There are 4 atoms in each molecule, so 2 moles will have 4*(1.204*10^24) atoms which is 4.816*10^24 atoms.

Each NaOH has one Na and one O and one H. Therefore, 2 NaOH has 6 atoms.
