Question

10×10²³ of molecules of NaOH=------------mole of NaOH​

Answer 1

NaOH Sodium hydroxide

Gram molecular Mass=Mass of Na+Mass of O+Mass of H

=23+16+1

=40g

Given mass=160g

No. of moles=

Gram Molecular Mass

Given mass

=

40

160

=4 mol

The moles of NaOH contained in 160g of it is 4 mole
