1)Molecular weight of water = 18g
Given weight = 9g
No. of mole = given weight ÷ molecular weight
So, moles of water = 9÷ 18 = 0.5 mol
1 mol contains 6.022 x 10^23
0.5 mol contains 6.022 x 10^23 ÷2
= 3. 011 x 10^23.
2)Ammonia, formed of 3 hydrogen atoms and a nitrogen atom, has an atomic weight of 17g/mol. (Actually 17.031g/mol if we’re being picky.)
This means that 17g of ammonia is one mole of ammonia.
The number of molecules in a single mole of any compound is given by Avoadro’s constant, which is 6.023x10^23.

i will mark u brainliest but 2 one??
I m not forcing u that's your choice but can u tell me 2 one question
17g of ammonia
well this one that i m tell u is through net...if u have no problem I'll tell u...
ok
have no objection
okk now u can see
by the way thanks
