Answer to Question #318044 in General Chemistry for arvi

Question

CALCULATE THE MOLALITY OF A SOLUTION CONTAINING 10.8 G OF ETHYLENE GLYCOL, C2H602, IN 360 G OF WATER.

Answer 1

2.3 ml of water occupy volume 2.3 cm3

So, one mole of a newly discovered crystalline substance occupies 2.3 cm3

The density of the crystal "= \\frac{m}{V} = \\frac{14.56}{2.3} = 6.33 \\;g\/cm^3"
