what is the molar mass of ch4? (c = 12.01 g/mol, h = 1.01 g/mol) a. 1 g/mol b. 4 g/mol c. 13.02 g/mol d. 16.05 g/mol enter the answer choice letter.
Answer
Explanation:
Step1: Identify the elements and their counts
$CH_4$ has 1 C - atom and 4 H - atoms.
Step2: Calculate molar mass of C part
The molar mass of C is $12.01$ g/mol. There is 1 C - atom, so contribution from C is $1\times12.01 = 12.01$ g/mol.
Step3: Calculate molar mass of H part
The molar mass of H is $1.01$ g/mol. There are 4 H - atoms, so contribution from H is $4\times1.01=4.04$ g/mol.
Step4: Calculate total molar mass
Total molar mass of $CH_4$ is $12.01 + 4.04=16.05$ g/mol.
Answer:
D. 16.05 g/mol
