A mixture of baking soda is prepared in water. The mass of this mixture is 225g. The original mass of baking soda was 50g. What is the original mass of water to which the baking soda was added?
A) 50g
B) 175g
C) 225g
D) 275g

Answer 1

It would have to be B 175. This is because if you subtract the baking soda from the total mass, you will get the original mass. 225-50=175. 

Answer 2

Answer: The correct option is C.

Explanation: We are given a mixture having baking soda and water.

Total mass of the mixture = 225 g

Original Mass of the baking soda= 50 g

Total mass of mixture= Original mass of Baking soda + Original mass of Water

Original mass of Water = (225 - 50)g

Original mass of water = 175 g.
