What is the number of grams of a solute for a 3L of a 2.5 M HCl solution???

To find the number of grams of a solute, you will need to use the molarity and the volume of the solution. Here's how you can calculate the number of grams of solute in a 3L solution of 2.5 M HCl:

1. Determine the molar mass of HCl:
The molar mass of HCl is the sum of the atomic masses of hydrogen (H) and chlorine (Cl). The atomic mass of hydrogen is approximately 1 g/mol, and the atomic mass of chlorine is approximately 35.5 g/mol. Therefore, the molar mass of HCl is approximately 36.5 g/mol (1 + 35.5 = 36.5).

2. Calculate the number of moles of solute:
Molarity (M) is defined as the number of moles of solute per liter of solution. In this case, the molarity is given as 2.5 M, which means there are 2.5 moles of HCl in 1 liter of solution. Since the volume of the solution is 3 liters, the number of moles can be calculated by multiplying the molarity by the volume:
Number of moles = 2.5 M × 3 L = 7.5 moles

3. Convert moles to grams:
To convert moles to grams, multiply the number of moles by the molar mass of HCl:
Number of grams = 7.5 moles × 36.5 g/mol ≈ 273.8 grams

Therefore, there are approximately 273.8 grams of HCl in a 3L solution with a molarity of 2.5 M.
