Answer 3

So, you have your starting product: \(\sf \color{red}{750~g}\) of glucose.
Now, first, make sure that your equation is balanced.
Always start with the given information first.
So, you take the \(\sf \color{red}{750~g}\) of Glucose \(\times\) molar mass of \(\sf \color{purple}{C_6 H_{12} O_6}\) this should cancel out units to get moles!
Remember that molar mass has units of \(\sf \frac{grams}{mol}\) so, you're dividing!

Answer 4

Once you have moles, note that you have a 1:2 ratio. Meaning, to get from moles of glucose to moles of \(\sf \color{red}{C_2H_5OH}\) you must multiply it by 2!
So, \(\sf mol~of~glucose \times\frac{2~mol~C_2H_5OH}{1~mol~C_6H_{12}O_6}\)
THEN you can finally find the mass by multiplying again by the molar mass of \(\sf C_2H_5OH \)

Answer 5

The units should cancel out.
