1 mol of `CH_(4)` contains

A

4 g atoms of hydrogen

B

`3.0` g atoms of carbon

C

`6.02 xx 10^(23)` atoms of hydrogfen

D

`1.81 xx10^(23)` molecules of `CH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
1 mol of `CH_(4) = 16` g of `CH_(4)`[molar mass]
Thus, 1 mol of `CH_(4) ` contains 4 g atoms of hydrogen.

0.1 mol of a carbonhydrate with empirical formula CH_(2)O contains 1 g of hydrogen. What is its molecular formula?

Most combustion reactions occur in excess of O_(2) (i.e., more than enough O_(2) to burn the substance completely). Calculate the mass of CO_(2) (in grams) produced by buring 4.00 mol of CH_(4) in excess O_(2) . Strategy: using the balanced equation {:(CH_(4), + 2O_(2), rarr CO_(2), + 2H_(2) O),(1mol, 2mol,1 mol,2mol),(16.0 g,2(32.0)g,44.0g,2(18.0g)):} we find out that 1 mol of CH_(4) is chemically equivalent to 1 mol of CO_(2) or 44.0g of CO_(2) .
