What is the mass (in grams) of 9.27x1024 molecules of methanol(CH3OH)
2 answers:
Moles of methanol = 9.27x10^24/6.02x10^23 = 15.398 moles.
Mass of methanol = moles of methanol x molar mass of methanol
= 15.398 x 32.042
= 493.38 grams.
Hope this helps!
Answer: 493 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number
of particles.
To calculate the number of moles, we use the equation:

1 mole of
weighs = 32 g
15.4 moles of
weigh = 
Thus mass of
molecules of methanol weigh 493 grams.
