In an experiment, mixing baking soda and vinegar produced a combination of salty liquid and carbon dioxide as shown in the following graph. What was the combined mass of the baking soda and vinegar before mixing?
A vertical bar graph shows two bars on a first quadrant coordinate plane. The horizontal axis has labels salty liquid and carbon dioxide, and the vertical axis labeled Mass in grams goes from 0 to 50 in increments of 10. The bar for salty liquid is at 45. The bar for carbon dioxide is at 10.
