Food was cooked, quickly frozen, and then dehydrated in a special vacuum chamber. Freeze-dried food didn't need to be refrigerated and would last a long time. To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water.
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%
The equation for the chi squared value is the (observed-expected)^2/E
