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 5 gms.?
[Hint : If the quantities of hydrogen and oxygen are 'x' and 'y' respectively,
then x:y=1:8 = 8x=y]​

Answer 1

Answer:

The answer is 1.5 g anmd 40g.

Step-by-step explanation:

Let hydrogen be x.

Let oxygen be y.

y=8x

Given Data:

oxygen, y=12 g

From the equation, we can write y=8x

12= 8x

x = 12/8=1.5 gm

Thus the quantity of hydrogen is 1.5 g

Now calculate the quantity of Oxygen when Hydrogen is 5g.

From the equation

y = 8x

y = 8 (5)

y = 40g

Thus the quantity of oxygen is 40g.

         

Answer 2

Step-by-step explanation:

let hydrogen be x

let oxygen be y

y=8x

y=12g

from the eqn we can write y=8x,12=8x

12/8=1.5

1.5=5

y=8x

y=8(5)

y=40

so, the quantity of oxygen is 40g
