Answer:

The main difference between cow and human digestive system is that cow exhibits a foregut fermenter digestion whereas human exhibits a simple monogastric digestion. Both digestive systems also differ by the type of teeth, mouth, stomach, gut, and digestive enzymes secreted by the gut.

The primary distinction between the digestive systems of cows and humans is that the former uses a foregut fermenter while the latter uses a straightforward monogastric digestion. The types of teeth, mouths, stomachs, guts, and digestive enzymes released by the gut also vary between the two digestive systems. Cows and humans have different digestive systems because they have evolved two different sorts of dietary patterns based on their capacities. The primary distinctions between the digestive systems of cows and humans are in the types of teeth, mouths, stomachs, and intestines, as well as the enzymes released.

Calculate the molar mass of a gaseous substance if 0.125 g of the gas occupies 93.3 mL at STP.
just olya [345]

Answer:

30.0g/mol

Explanation:

Step 1: Given data

  • Mass of the gas: 0.125 g
  • Pressure (P): 1 atm (standard pressure)
  • Temperature (T): 273.15 K (standard temperature)
  • Volume (V): 93.3 mL

Step 2: Calculate the moles of the gas

We will use the ideal gas equation.

P \times V = n \times R \times T\\n = \frac{P \times V}{R \times T} = \frac{1atm \times 0.0933L}{\frac{0.0821atm.L}{mol.K}  \times 273.15K} = 4.16 \times 10^{-3} mol

Step 3: Calculate the molar mass of the gas

4.16 × 10⁻³ moles correspond to a mass of 0.125 g. The molar mass of the gas is:

\frac{0.125g}{4.16 \times 10^{-3} mol} =30.0g/mol
