Question

1. bridget mixed soy sauce, rice vinegar, and sesame oil together in a bottle to make 450 grams of sauce. she put the bottle of sauce in her kitchen cabinet.
2. a week later, bridget took the bottle out of her cabinet and saw that there had been a change. the sesame oil had separated from the soy sauce and rice vinegar. there were 400 grams of the soy sauce and rice vinegar mixture. there was also some sesame oil floating on top.
3. complete the bar graph to show the mass of the sesame oil.
4. masses before and after the change

bar graph with y - axis labeled mass (grams) from 0 to 500, x - axis categories: sauce, soy sauce and rice vinegar, sesame oil. the bar for sauce is 450 grams (red), the bar for soy sauce and rice vinegar is 400 grams (green), and the bar for sesame oil is to be completed.

Explanation:

Step1: Determine total mass before

The total mass of the sauce before separation is 450 grams (soy sauce + rice vinegar + sesame oil).

Step2: Determine mass of non - oil part after

After separation, the mass of soy sauce and rice vinegar (non - sesame oil part) is 400 grams.

Step3: Calculate mass of sesame oil

To find the mass of sesame oil, we subtract the mass of the soy sauce and rice vinegar mixture from the total mass of the sauce before separation. Using the formula \( \text{Mass of sesame oil}=\text{Total mass of sauce}-\text{Mass of soy sauce and rice vinegar mixture} \), we substitute the values: \( 450 - 400=50 \) grams. So the bar for sesame oil should reach up to 50 grams on the y - axis.

Answer:

The mass of the sesame oil is 50 grams, so the bar for sesame oil in the graph should be drawn to represent 50 grams.
