Answer to Question #173397 in General Chemistry for meka

Question

CH₃COOH, contains 1.80 x 10²³ carbon atoms. How many moles of acetic acid are in the sample

Answer 1

CH₃COOH contains 2 atoms of carbon , 4 atoms of hydrogen and 2 atoms of oxygen

no. Of carbon atoms = moles × 6.022×10²³

1.80×10²³ = moles × 6.022×10²³

moles of carbon = 0.298 moles

moles of oxygen = 0.298 moles

moles of hydrogen = 0.596 moles

Moles of CH₃COOH = 0.596 + 0.298 + 0.298

Moles of CH₃COOH = 1.192 moles
