How to understand the questions correctly

Postby May Xiao 1H » Sun Oct 07, 2018 9:45 pm

Hi,

I'm doing the questions on the book and get a little confused by some FAQ. So I want to ask is my statement below is true:
-When the question ask "amount": it's asking the moles
-When the question ask "number": it's asking number of objects (N)
-When the question ask "weight": it's asking molar mass (M)
?

Thx for the ones that would like to answer~

I think it really depends on the question. On the test we will make this very clear. However, I think sometimes when a question asks for "amount" it can sometimes be asking for grams (i.e. in yield questions), and weight may also sometimes refer to grams. If you have any specific examples you can share them here.

In general I think those statements are true. Most of the questions should clearly state what form they want the answer with, and I'm sure it will be very clear on the test.

On the test, the questions will most likely specify what units they want the answer in. And if they tell you to to find for example "mass" without units, I assume we should use the base SI units?
