Question

The ratio of molecular weight of Hydrogen and Oxygen in water is 1: 8. Set up an equation between Hydrogen and Oxygen and draw its graph. From the graph find the quantity of Hydrogen if Oxygen is 12 grams and quantity of oxygen if hydrogen is \( \frac{3}{2} \) gms.? [Hint : If the quantities of hydrogen and oxygen are ' \( x \) ' and ' \( y \) ' respectively. then \( x: y = 1 : 8 \Rightarrow 8x = y \) ].

Answer 1

Let the quantity of Hydrogen = x grams 

And the quantity of Oxygen = y grams 

By problem 8x = y ⇒ 8x – y = 0

x	1	2	4	5
y	8	16	32	40

From the graph, the quantity of Hydrogen 

if Oxygen is 12 gm = 3/2 g.

From the graph, the quantity of Oxygen 

if Hydrogen is 3/2 g = 12 g.
