Chapter 13, Problem 118E

Interpretation Introduction

Interpretation:

“molecular formula of a compound” should be identified.

Concept introduction

a) The osmotic pressure is a colligative property and depends on concentration as

πV = nRT

π = osmotic pressure

b) The combustion of one mole of carbon gives one mole of CO₂, the equation is

${\text{C(s)+O}}_{\text{2}}\text{(g)}\to {\text{CO}}_{\text{2}}\text{(g)}$

c) The combustion of one mole of hydrogen will give one mole of H₂O, the equation is

${\text{H}}_{\text{2}}\text{(g)+0}{\text{.5O}}_{\text{2}}\text{(g)}\to {\text{H}}_{\text{2}}\text{O}$
