Welcome
what is the valency of H2So4?
kya hua didi?
??
VALENCY OF H2SO4.
the H is +1 and there are 2 of them for a total of +2
The O is -2 and there are 4 of them for a total of -8
So the S has to be +6 in order to make the entire compound neutral
So then you have +2 for H, +6 for S and -8 for the O...

Explanation:
★ Avogadro Number ★
→ one mole is the collection of 6.02 × 10^(23) entities . It is given as separate name & symbol known as Avogadro constant denoted by NA . Entities may represent atoms , ions , molecules or even pens , chair, paper etc also include in this but as this number (NA) is very large therefore it is used only for very small things.
