Question

how many mole of NaOH is presentnin 160g of it

Answer 1

40g of NaOH contain 1 mole
1g. of NaOH contain 1/40 mole
160g of NaOH contain 1/40*160 moles
= 4 moles

Answer 2

Answer:

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
