If your first distillate was 49 mole percent methanol how many theoretical plates were in your distillation setup?

There is quite a bit of missing information here.
a. Lets assume your pressure is 1 atm.
b. Lets also assume you are distilling methanol and water.
c. Lets assume your theoretical plate efficiency is 100%
d. Lets ALSO assume your initial concentration is 0.1 mol% methanol.
Given these condition it takes about 1.25 theoretical plates to distill it to about 49 mol%.
The number of plates depends heavily on the initial concentration.
Working backwards from 49mol%, exactly one stage would place you at an initial concentration of about 8%. Exactly two would place you at about 1 mol%.

If the actual yield of Mg3N2 is 47.87 g and the theoretical is 50.26 g What is the percent yield?
Percent yield = Actual Yield / Theoretical Yield * 100 hope that helps :)
What percent alcohol is methylated spirits?

Would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
because of variable in the situation '
How do you prepare 30 percent of methanolic KOH solution?
Dissolve 30 g KOH in 100 mL methanol.
Would the percent yield be different if the actual yield and theoretical yield were in units of moles?
Not at all. Just be consistent with the units of both actual and theoretical yield.
What is the final percent concentration of the solution when 600 ml of 100 percent methanol added to 4400 ml of water?
13.6% methanol solution.
Is that 50 percent methanol damage membranes more or 25 percent acetone?
50% methanol will damage the membrane more than 25% acetone. we did the lab.
How do you show percent error?
Percent error = (actual value - theoretical value) / theoretical value * 100%
What is the percent by volume of 25 ml of methanol in 75 ml of water?
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
Formula for percent error?
Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100

Do methanol kill bacteria?
Yes, methanol does kill bacteria, especially if it is 70 percent or more, this allows penetration of the cell wall of the organism.
