We used a buret today, and I don't get how to calculate volume. I have an initial reading of 49.97 and a final buret reading of 30.49. How do I get the volume? I thought I just subtracted the final from the initial, but someone said their tutor told them to take 50-their initial, and add whatever that amount is to their final to get the volume. Is that how to do it?

I don't get what you did? Burets usually are used to measure the volume taken FROM the buret and the final reading is greater than the initial volume. You seem to be adding to the buret. Explain what you did. If you want the volume that was ADDED you subtract 49.97-30.49. If you want the volume that is in the buret after adding, you subtract 50-30.49 which is the same as (50.00-49.97) + (49.97-30.49) = ?
