5.2/ 24.3 = 0.214
0.214 x 2 = 0.428
0.428 x 36.5= 15.6g
Answer:
Explanation:
To find how many moles are in the sample, you first must calculate how much one mole of C2H5OH weighs.
2(mass of C) + 5(mass of H) + (mass of O) + (mass of H)
= 2(12.01) + 5(1.008) + (16.00) + (1.008) = 46.068 g/mol
So, now that we know what 1 mole weighs, we can simply divide the weight of the sample by the weight of a mole of ethanol to get our answer.
39.2 / 46.068 = approximately 0.851 mol of ethanol
Explanation:
The main additive has traditionally been 10% methanol, giving rise to the term "methylated spirits". Other typical additives include isopropyl alcohol (IPA), acetone, methyl ethyl ketone (MEK), and methyl isobutyl ketone (MIBK). CAS number depends on denaturant used.
