Question

most density is 13.6 find the moles of 1 litre of it mass is 200

Answer 1

Molar mass of HG =200 g
1l of metal =1000³
Mass of Mercury = Density ×Volume
=13.6×1000
Moles of Mercury in 13600g
=136000÷200
=68 moles

Answer 2

Molar mass is 200 so
Volume 1 L
Mass is 13.6*1000. Mass is 13600
Molar mass is 68
