To determine the total mass of the mixture, we need to sum the masses of all the components involved. Let's break it down step by step:
1. We start with 16 grams of salt.
2. We then have 22 grams of baking soda.
3. Lastly, we have 462 milliliters of water. Since the density of water is approximately 1 gram per milliliter, 462 milliliters of water is equivalent to 462 grams.
Now, we need to find the total mass of the mixture by adding these components together:
[tex]\[
16 \, \text{grams (salt)} + 22 \, \text{grams (baking soda)} + 462 \, \text{grams (water)}
\][/tex]
Adding these together:
[tex]\[
16 + 22 + 462 = 500 \, \text{grams}
\][/tex]
Therefore, the total mass of the mixture is 500 grams.
