Question

The ratio of hydrogen and oxygen in water is 1:8. setup an equation between hydrogen and oxygen and draw its graph. From the graph find the amount of hydrogen if oxygen is 12g?

Answer 1

Let hydrogen be x.

let oxygen be y.

y=8x.



Given oxygen, y=12

From the equation y=8x,

12= 8x

x = 12/8=1.5 gm

Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of ratio and proportion will help us to solve this question.

Given:

The ratio  in water of hydrogen and oxygen is $1:8$. According to the graph ,  the amount oxygen is $12g$ .

To Find:

We have to draw the graph and get the amount of the hydrogen if the amount of oxygent is $12g$ .

Solution:

Consider the amount of hydrogen is $x$ and the amount of oxygen is $y$ .

So we can write $y=8x$ .

the amount of oxygen is $12g$ which is given in the question.

The equation can be written as $12=8x$ .

The value of $x$ is $x=\frac{12}{8} =1.5 g$.

The amount of hydrogen is $1.5g$ if the oxygen is $12g$ .
