First, calculate the molar mass of CH3OH
Atomic weight of carbon = 12.0107
Atomic weight of hydrogen = 1.00794
Atomic weight of oxygen = 15.999
Molar mass of CH3OH = 12.0107 + 4 * 1.00794 + 15.999 = 32.04146
Now determine how many moles you have by dividing the number of atoms by avogadro's number
moles = 9.83 x 10^24 / 6.0221409 x 10^23 = 16.3231
Now multiply the number of moles by the molar mass
16.3231 * 32.04146 = 523.0159557
Since we only have 3 significant figures, round the result to 3 significant figures.
523.0159557 grams = 523 grams</span>
