Question

How many moles of CH4 are present in a sample of 10.55 grams of CH4? (The molar mass of CH4 is 16.05 grams/mole). If you are unsure how to convert grams to moles, please see the example problem linked HERE. a 26.6 moles of CH4 b 1.52 moles of CH4 c 0.657 moles of CH4 d 169.3 moles of CH4

Answer 1

The number of moles of CH4 present can be calculated using the formula:

Number of moles = Mass / Molar mass

Plugging in the values:
Number of moles = 10.55 grams / 16.05 grams/mole ≈ 0.657 moles

Therefore, the answer is c) 0.657 moles of CH4.
