Our food is our energy. When we eat food, we need to digest it and the eaten food, once digested, serves as our energy that we use up for daily needs. If we eat too much food, it will be store and we will become overweight over time. If we don't eat enough, we will lose weight because we're not getting enough energy in our bodies, so our bodies cannot get enough energy from the food eaten, so it looks elsewhere for stored energy - our fat and muscle cells.
18 g
Explanation:
Remember that 1g is equivalent to 1 ml;
1g = 1 mL
100 g = 100 mL
Therefore in an 18% NaOH solution, for every 100 mL, there is 18 g of dissolved NaOH. This is how we derive the percentage solution;
18 g / 100 g = 18%
