Question

How many gms of Hg are present in 225gm of pure HgS..Hg-200,S-32​

Answer 1

Answer:

194.94 gram Hg in 225 gram HgS.

Explanation:

So here mass of HgS given=225 gram.

Molecular mass of HgS is 200.6+32=232.6 gram.

Hence moles present in given mass=225/232.6=0.94 grams.

As you know in 1 mole of HgS there is one mole of Hg.

So in 0.94 moles of HgS there will be 0.94 moles of Hg.

As mass is asked we know mass=moles× molecular mass=0.94×200.6=194.04 gram.

So it exists 194.94 gram Hg in 225 gram HgS.

Answer 2

Molar mass of HgS =200.6+32=232.6 gm mol−1

Mass of Hg in 232.6 gms of HgS=200.6 gms

Mass of Hg in 225 gm of HgS=200.6/232.6 × 225

Ans: 194.04g
