Question

carbon and oxygen react in ratio 3 ratio 8 by mass to form CO2 what weight of carbon should be used to react completely with 32 gram of oxygen

Answer 1

Carbon and oxygen react in a ratio of 3:8

Let the mass be x
So
They will react in a ratio of

3x : 8x
So,

Given that mass of oxygen is 32 g
So,

8x = 32
Or.
X = 32/8 = 4

So,

3x grams of carbon will react with 32 gram of oxygen.
So,

Mass of carbon = 3 *4 = 12 g

So.

12 grams of carbon will completely react with 32 gram of oxygen.

Answer 2

Answer:

Carbon and oxygen react in a ratio of 3:8

Let the mass be x

So

They will react in a ratio of

3x : 8x

So,

Given that mass of oxygen is 32 g

So,

8x = 32

Or.

X = 32/8 = 4

So,

3x grams of carbon will react with 32 gram of oxygen.

So,

Mass of carbon = 3 *4 = 12 g

So.
