How many moles are in 80 g of NaOH?

How many molecules are present in 80 grams of sodium hydroxide?

In 80 grams there will be 2 molecules of NaOH, so mass of Sodium would be 23 x 2 = 46g.

How many moles are there in 60 g of NaOH?

Answer : The number of moles in 60 g of NaOH is 1.5 moles.

How many moles are in 30g of NaOH?

The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30.

How many moles are present in 4 grams of sodium hydroxide?

=0.10 (approx.)

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

How many grams of NaOH are in 3 moles of NaOH?

A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30.

What is the mass of 0.5 mole of sodium hydroxide?

However, in expressing the concentration as M (molarity) the volume of the solution is also taken into account. Thus, 0.5 mole of NaOH represents simply 20 g of the base while 0.5 M means 20 g of the base or NaOH dissolved per litre of the solution.
