Question

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.

Answer 1

In the experiment described, mixing baking soda and vinegar produced a salty liquid and carbon dioxide. The vertical bar graph shows the masses of the salty liquid as 45 grams and carbon dioxide as 10 grams.

To find the combined mass of the baking soda and vinegar before mixing, we can add the mass of the salty liquid and the mass of the carbon dioxide:

\[
\text{Total Mass} = \text{Mass of Salty Liquid} + \text{Mass of Carbon Dioxide}
\]
\[
\text{Total Mass} = 45 \, \text{grams} + 10 \, \text{grams}
\]
\[
\text{Total Mass} = 55 \, \text{grams}
\]

So, the combined mass of the baking soda and vinegar before mixing is **55 grams**.
