In а synthesis оf 4-methylcyclоhexene by dehydrаtiоn of cyclohexаnol (see the equation given below), you start with 0.22 grams of the alcohol. The molecular weight of 4-methylcyclohexanol is 114.19 g/mol. How many molecules of alcohol is this? Problem viewing the image, Click Here   You will need to know that a mole of a substance is equal to Avogadro's number (6.022 x 1023) of molecules of that substance.  Give the number of molecules to 3 significant figures, and do not use scientific notation. Include all of the zeros in your answer (we want you to see how large the number of molecules is). In addition, write down the number of zeros you included in parentheses.  For example, if one of your answers is 6.022 x 1023, then you would write it as follows:  602000000000000000000000 (21 zeros).
