Swamp gas consists primarily of methane, a chemical compound consisting of a 1 : 4 ratio of carbon to hydrogen atoms. if a sample of methane contains 1564 hydrogen atoms, how many carbon atoms are present in the sample?

Number of carbon atoms present in the sample are 391.

Step-by-step explanation:

We are given that,

Ratio of carbon to hydrogen atoms = 1 : 4

It is given that a sample of methane consists of 1564 hydrogen atoms.

Let the carbon atoms in the sample = x

So, we have the relation,

i.e.

i.e.

i.e. x= 391

Hence, the number of carbon atoms present in the sample are 391.

this doesn't make sense lol

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
