How many moles are in sodium?

In grams, a mole is one formula mass. For example, 1 mol of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table).

What is number of mole?

The mole is a measure or the base unit for the amount of substance present in the given sample. 1 mole is number which is equal to 6.022 x 1023 particles, also known as the Avogadro’s constant. These particles can be any type of species, e.g atoms, molecules, electrons, protons, neutron etc.

How many moles of NaOH are in 8.00 g?

The answer is 39.99711.

How many moles are there in 20g of NaOH?

Number of moles which make up 20 grams of NaOH = (20 grams × 1 Mole)/(40 grams) = 0.5 moles.

How do you find the moles of NaOH?

Step 1: Calculate the amount of sodium hydroxide in moles

  1. Amount of solute in mol = concentration in mol/dm 3 × volume in dm 3
  2. Amount of sodium hydroxide = 0.100 × 0.0250.
  3. = 0.00250 mol.
  4. The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2O(l)
  5. So the mole ratio NaOH:HCl is 1:1.
