Answer:
Colloids are those solution which exhibit Tyndall effect or scatter light.
Molarity is the most convenient way to express concentration.
Mathematically, molarity is expressed as

In present case,
mass of solute (KCl) = 36 g
molecular weight of KCl = 74.55 g/mol
volume of solution = 100 ml = 0.1 l
∴ Molarity =

= 4.829 M
Thus, conc. of saturated KCl at 20 oC is 4.829 M

Explanation:
According to the United States Department of Agriculture (USDA), Texas had 4,015,000 beef cows in 2013. One beef cow produces 205 grams of methane per day. The methane produced by the beef cows in Texas per day is:

Each year has 365 days. The methane produced by the beef cows in Texas per year is:
