Question

if 42 g of H2 in a sample of pure methane (ch4). how many grams of carbon present​

Answer 1

Answer:

Therefore,  

16.0426 g

of  

CH

4

would have  

12.011 g C

, and so, in  

10 g CH

4

, there would be

0.7487

×

10 g CH

4

=

7.487 g C

Answer 2

126g of Carbon is present in the Sample of Pure methane.

GIVEN: 42 g of H2 in a sample of pure methane (ch4)
TO FIND Composition of Carbon in the given Sample.
SOLUTION:

As we are given in the question,

A sample of Methane (ch4) is provided.

There are 42 grams of H2 which means hydrogen in the provided sample.

As we know,

Methane is an element that contains four atoms of H2, that is hydrogen, and 1 atom of Carbon.

It is one of the most simple alkalines and belongs to group-14 hydroxide.

Carbon is attached by single bonds to Hydrogen.

To find the composition of Carbon we know,

n(H)=1g/mol42g​=42mol

n(C)=41​n(H)=442mol​=10.5mol

m(C)=10.5mol×12g/mol=126g

Therefore,

126 grams of Carbon are present.
