Question

1. The ratio of molecular weight of Hydrogen and Oxygen in water is 18. Set up an equation
between Hydrogen and Oxygen and draw its graph. From the graph find the quantity of
3
Hydrogen ifOxygen is 12 grams. And quantity of oxygen if hydrogen is 5 yms.?​

Answer 1

Step-by-step explanation: Given, The ratio of molecular weight of Hydrogen and Oxygen in water is 1 : 8

Let the amount of hydrogen be x and amount of oxygen be y

Given, x : y = 1 : 8

=> x/y = 1/8

=> y = 8x ..............1

Now, the graph is:

Again, given oxygen = 12 gm

Now, amount of hydrogen is

    12 = 8x

=> x = 12/8

=> x = 3/2

=> x = 1.5 gm

Again given quantity of hydrogen = 32 gm

So, the quantity of oxygen is

     y = 8*32

=> y = 256 gmsGiven, The ratio of molecular weight of Hydrogen and Oxygen in water is 1 : 8

Let the amount of hydrogen be x and amount of oxygen be y

Given, x : y = 1 : 8

=> x/y = 1/8

=> y = 8x ..............1

Now, the graph is:

Again, given oxygen = 12 gm

Now, amount of hydrogen is

    12 = 8x

=> x = 12/8

=> x = 3/2

=> x = 1.5 gm

Again given quantity of hydrogen = 32 gm

So, the quantity of oxygen is

     y = 8*32

=> y = 256 gms
