If you have 38 grams of CH4 how many moles of CH4 do you have
0.42 moles
2.3 moles
609.6 moles
38 moles

2.3 moles

Explanation:

From the question given, we obtained the following data:

Mass of CH4 = 38g

Molar Mass of CH4 = 12 +(4x1) = 12 + 4 = 16g/mol

Number of mole =?

Number of mole = Mass /Molar Mass

Number of mole CH4 = 38/16 = 2.3mol

the correct answer would be d. hope this !
