What is the number of grams of a solute for a 3L of a 2.5 M HCl solution???
To calculate the number of grams of a solute for a given solution, you need to know the molar concentration of the solute (Molarity) and the volume of the solution.
In your case, we have:
Molarity (M) = 2.5 M
Volume (V) = 3 L
To calculate the number of grams of solute, you can use the formula:
Number of grams = Molarity (M) × Volume (L) × Molar mass (g/mol)
First, let's determine the molar mass of HCl:
The molar mass of hydrogen (H) is approximately 1.008 g/mol.
The molar mass of chlorine (Cl) is approximately 35.453 g/mol.
Adding these two values, we get:
Molar mass (HCl) = 1.008 g/mol + 35.453 g/mol = 36.461 g/mol
Now, we can calculate the number of grams of HCl:
Number of grams = 2.5 M × 3 L × 36.461 g/mol
By multiplying these values, we find:
Number of grams = 273.4585 g
Therefore, there are approximately 273.4585 grams of HCl in a 3L, 2.5 M HCl solution.
