Question

CALCULATE THE MOLES OF SODIUM HYDROXIDE CONTAINED IN 160 GRAM OF IT

Answer 1

GMM of NaOH=23+1+16

                       =40g

Number of moles in 160g=160/40

                                         =4

Answer 2

Hello dear user!

A mole is the amount of a substance that contains as many atoms, molecules or ions as there are atoms in 0.012 kg of the carbon 12 Isotopes.

e. g.

1 mole of hydrogen contains 6.022 × 10 ^ 23.

Or

1 mole of sodium contains 6.022 × 10 ^ 23.

The SI unit of amount of substance is mole ( written as mol ).

Question = Calculate the moles of Sodium hydroxide contained in 160 g of it.

Answer = 160 g of Sodium hydroxide.

Molar mass of Sodium hydroxide ( NaOH ) ⇒

Sodium = 23

Oxygen = 16

Hydrogen = 1

= 23 + 16 + 1

= 40 g

40 g of Sodium hydroxide = 1 mol

160 g of Sodium hydroxide = 1 mol × 160 /  40 = 4 mol.

Hence  " 4 moles contained in 160 g of sodium hydroxide.

Sodium hydroxide is industrially produced using the electrolytic chloralkali process.

Thanks!
