HNO3 and NaOH

Take helps

Atomic masses of some elements : H(1) ,O(16), S(32),N(14),Na(23)

Answer 1

Its your and. Hope it will definitely help you

Answer 2

Hello friend

___________________________


i.) HNO3

==> Molecular mass of HNO3

==>(Atomic number of H) x 1 +(Atomic mass of N) x 1 + (Atomic mass of O) x 3

==> (1 x 1) + (14 x 1) + (16 x 3)

==> 1 + 14 + 48

==> 63

: Molecular mass of HNO3 = 63


ii.) NaOH

==> Molecular mass of NaOH

==> (Atomic mass of Na) x 1 +( Atomic mass of O) x 1 + (Atomic mass H) x 1

==> (23 x 1)+ (16 x 1) + (1 x 1)

==> 23 + 16 + 1

==> 40


: Molecular mass of NaOH = 40



Thanks..
