What is the molarity of a solution made by dissolving 21.2 g of sodium hydroxide (naoh) in enough water to make 7.92 l of solution?

molar mass na: 22.99 g/mol
molar mass o: 16.00 g/mol
molar mass h: 1.008 g/mol

M = mol/L so add all molar masses together then divide 21.2g/(molar mass) then divide by Litres

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
