How many grams of sodium hyrdioxde are in 251.0ml f 0.600m
Furkat [3]

Answer:

There are 6.024 grams of sodium hydroxide in the solution.

Explanation:

Molarity=\frac{Moles}{Volume (L)}

Moles (n)=Molarity(M)\times Volume (L)

Moles of sodium hydroxide = n

Volume of sodium hydroxide solution = 251.0 mL = 0.251 L

Molarity of the sodium hydroxide = 0.600 M

n=0.600 M\times 0.251 L=0.1506 mol

Mass of 0.1506 moles of NaOH :

40 g/mol\times 0.1506 mol = 6.024 g

There are 6.024 grams of sodium hydroxide in the solution.

A laboratory requires 2.0 L of a 1.5 M solution of hydrochloric acid (HCl), but the only available HCl is a 12.0 M stock solutio
ira [324]
The amount of the solute is constant during dilution. So the mole number of HCl is 2*1.5=3 mole. The volume of HCl stock is 3/12=0.25 L. So using 0.25 L stock solution and dilute to 2.0 L.

<h3>What do we know about the process of dissolution?</h3>

A solute can dissolve in a solvent in a solid, liquid, or gaseous phase to create a solution through the process of dissolution. Solubility. The greatest amount of a solute that may dissolve in a solvent at a particular temperature is known as its solubility. The solution is said to as saturated when the maximum amount of solute is present.

Several variables influence solubility, including:

  • The solute's concentration
  • The system's temperature
  • Pressure (for gases in solution)
  • The solvent's and solute's polarity
