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!

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 $$\sf C_2H_5OH$$

The units should cancel out.
