Convert 0.880 moles of sucrose to cups of sugar

Sagot :

Answer:

2.00 Cups

Explanation:

This question isn't really possible without the density of the sugar, you can pack it tighter like if you have sugar cubes for example, but a quick search gives a density of 1.59 g/mL, so that what I will use.

Let's get the number of grams of sucrose (molar mass 342.3 g/mol) we have by taking 342.3 g/mol * 0.880 mol. Moles cancel and we get 301.224 grams of sucrose.

Now we just need to take the density, there is one mL for every 1.59 grams of sucrose, so we will take (301.224 g)/(1.59 g/mL). grams cancel and we are left with 478.94616 mL.

The question asked for cups (I'm assuming US cups) though, so let's convert by dividing by 240 to give us 1.995609 cups. Or when we round to sig figs we get 2.00 cups.
