Answer:
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.
Answer: x=28
Step-by-step explanation:−2(3x−9)+5x=−10
(Distribute)
(Combine Like Terms)
Step 2: Subtract 18 from both sides.
Step 3: Divide both sides by -1.
