If I have 6 grams of CaBr2 in 14L , and I have to find the following: 1. % mass/ volume concentration
2. Molarity
3. Osmolarity

I did the question already but my professor said to check double check the mass in original statement versus the mass you used in calculations.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
