Question

mass of water and NaoH

Answer 1

Hola friend!!
Rajdeep here...

If you are asking for the Relative molecular mass of water and sodium hydroxide, here's your answer:

Atomic mass of:
Na = 23
O = 16
H = 1

Hence, mass of water (H2O)
= 2x1 + 16 = 18

Mass of Sodium hydroxide (NaOH) 
= 23 + 16 + 1
= 40

Thanks!!
