The simplest form of the molecular formula for methanol {note corrected spelling} is CH4O, and its gram molecular mass is 32.04. By definition therefore, a mass of Avogadro's Number of molecules contains 32.04 grams. Avogadro's Number is about 6.022 X 1023. Therefore, 9.47 X 1024 molecules of methanol contains [(9.47 X 1024)/(6.022 X 1023)]32.04 or 504 grams, to the justified number of significant digits.

How many molecules are in 720 grams of C6H12O6?
To determine the number of molecules in 720 grams of C6H12O6 (glucose), you first need to calculate the number of moles present. The molar mass of glucose is 180.16 g/mol. Dividing 720 grams by the molar mass gives you 4 moles of C6H12O6. One mole of any substance contains Avogadro's number of molecules, which is approximately 6.022 x 10^23. Therefore, 4 moles of C6H12O6 would contain about 2.409 x 10^24 molecules.

How many grams are in 8.2 x 1022 molecules of NCl3?
To convert molecules to grams, first find the molar mass of NCl3: Nitrogen (N) has a molar mass of 14.01 g/mol, and chlorine (Cl) has a molar mass of 35.45 g/mol. Therefore, the molar mass of NCl3 is 14.01 + (3 * 35.45) = 120.36 g/mol. Now, use this molar mass to convert molecules to grams: 8.2 x 10^22 molecules * (1 mol / 6.022 x 10^23 molecules) * 120.36 g/mol ≈ 16.06 grams.
What is the mass of 2.50 moles of oxygen gas?
The relationship between number of moles and mass is: n = m/MW Where n is the number of moles, m is the mass in grams and MW is the molecular weight (or molecular mass).
