Molecular Mass of Compound.

\\ \sf\longmapsto Ba_3(PO_4)_2

\\ \sf\longmapsto 3(137u)+2(39u+4(16u))

\\ \sf\longmapsto 411u+2(39u+64u)

\\ \sf\longmapsto 411u+2(103u)

\\ \sf\longmapsto 411u+206u

\\ \sf\longmapsto 617u

  • Molecular mass of O in compound=16(4)=64u

\\ \sf\longmapsto Mass\%\:of\:O

\\ \sf\longmapsto \dfrac{64}{617}\times 100

\\ \sf\longmapsto \dfrac{6400}{617}

\\ \sf\longmapsto 10.3\%

What is the maximum number of hydrogen bonds that can be formed in a sample containing 1.0 mol (NÅ molecules) liquid HF? Compare
MAVERICK [17]

Answer:

Explanation:

In one mole of liquid HF , no of molecules is 6.02 x 10²³.

Each molecule forms two hydrogen bonds on an average so no of hydrogen bonds per mol ih HF is

2 x  6.02 x 10²³.

= 12.04 x 10²³ .

In water no of hydrogen bonds per molecule of water is 4 . So in one mole of water no of hydrogen bonds is

4 x 6.02 x 10²³.

= 24.08 x 10²³ .
