Answer: amount of substance n = cV = 2.0 mol/l x 0.25 l = 0.50 mol
Explanation:
Answer:
Lava is hot liquid rock. When lava flows over solid ground, the solid ground beneath it increases in temperature. What happens to the molecules in the solid ground when the temperature is increasing? The energy of the molecules in the ground decreases.
(2.5)(10000)=25000
25000 * 3785
ML = 94635294.6 milliliters
Answer: Molarity of the solution is 0.813 M.
Explanation:
Given : Mass of NaOH = 97.68 g
Volume of solution = 3 L
The molar mass of NaOH is 39.99 g/mol. Hence, moles of NaOH are calculated as follows.

Molarity is the number of moles of solute present in a liter of solution. Therefore, molarity of given solution is calculated as follows.

Thus, we can conclude that molarity of the solution is 0.813 M.
