A 20% baking soda solution weighing 420 g was added with a 10% baking soda solution weighing 180 g. What is the concentration of baking soda in the mixture?
The desired concentration of baking soda in the new solution is determined using the conditional variable “Y”.
Based on the data of the problem, we have the following equation: Y = ((0.2 x 420 + 0.1 x 180) / (420 + 180)) x 100.
As a result of solving the existing equation, we get the following Y = ((84 + 18) / 600) x 10 = (102/600) x 100 = 17%.
Answer: The concentration of baking soda in the new solution is 17%.
