Question

Calculate the atomic mass in grams of 0.35 moles of CH4

Answer 1

First, you must know the molecular mass of CH4. (how many grams in one mole)
C=12g
H=4g
So since the molecular mass is 16 grams, just multiply your given number of moles, .35 moles, by the molar mass, 16. That will give you a final answer of 5.6 grams of CH4.

Hope this helps!

Answer 2

Answer: 5.6 grams

Step-by-step explanation:

To calculate the moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

Thus mass =
`{\text {number of moles}}* {\text {Molar mass}}`

For
`CH_4`

Moles of
`CH_4`= 0.35 moles

Molar mass of
`CH_4` = 16 g/mol

Putting values in above equation, we get:

mass =
`0.35moles* 16g/mol=5.6 g`

The atomic mass of 0.35 moles of
`CH_4` is 5.6 grams.
