I believe it's Hirsutism, maybe list options if there are any next time! :)
Answer:
When you know the number of moles that you expect, you will multiply by the molar mass of the product to find the theoretical yield in grams. example, the molar mass of CO2 is about 44 g/mol. (Carbon's molar mass is ~12 g/mol and oxygen's is ~16 g/mol, so the total is 12 + 16 + 16 = 44.)Explanation:
Answer:
Both can hunt for their food (heterotrophs), but euglena can also make their own food (autotroph) with its chloroplasts. Amoeba have pseudopods to move/eat, but euglena have flagella to move. How are euglena and paramecium similar and different? ... Both also use flagella to move, but volvox move together in colonies.

Explanation:
<u>1. Balanced chemical equation</u>
- Ba(OH)₂(aq) + 2HNO₃(aq) → Ba(NO₃)₂(aq) + 2H₂O(l)
<u />
<u>2. Determine the number of moles of HNO₃ in the solution</u>
- n = M × V = 0.425M × 0.050 liter = 0.02125 mol HNO₃
<u>3. Use the mole ratio from the balanced chemical equation and the number of moles of HNO₃ to determine the number of moles of Ba(OH)₂.</u>
<u>4. Determine the molar concentration of the solution of Ba(OH)₂</u>
- M = 0.010625mol/0.0368liter
From the question, the molarity of the desired solution was given as 0.235 M while the volume of the solution is 250 mL. Molarity is a unit of concentration used for solutions. It is necessary to first define what molarity is to be able to answer the question. Molarity is defined as number of moles of solute divided by the volume of the solution.
In this case, the amount of solid KCl required to obtain a concentration of 0.235 M in a volume of 250 mL is to be determined. The molar mass of KCl will also be used as conversion factor from unit of moles to grams. The value is 74.5513 g/mol. The following equation is used:
0.235 mol/ L x 1 L/1000 mL x 250 mL x 74.5513 g/mol KCl = 4.3799 g KCl
Thus, 4.38 g KCl is required to prepare 250 mL of 0.235 M solution.
