How many moles of the solute h2so4 is needed to prepare 5 L of a 2 M solution of h2so4
mols = M x L = 2M x 5L = ?
molarity is moles per liter of solution
5 L * 2 M = ? moles
To determine the number of moles of solute (H2SO4) needed to prepare a 2 M solution in a volume of 5 liters, follow these steps:
Step 1: Write down the given information.
- Volume of solution (V) = 5 L
- Concentration of solution (C) = 2 M
Step 2: Use the formula for molarity to find the number of moles of solute.
- Molarity (M) = Moles of solute (n) / Volume of solution (V)
Rearrange the formula to solve for moles of solute (n):
- n = M × V
Step 3: Substitute the given values into the formula and calculate.
- n = 2 M × 5 L = 10 moles of H2SO4
So, you would need 10 moles of H2SO4 to prepare a 5 L solution with a concentration of 2 M.
To calculate the number of moles of the solute (H2SO4) needed to prepare a 2 M solution in 5 L of solvent, you can follow these steps:
Step 1: Identify the formula and molarity of the solution.
The formula of the solute is H2SO4, and the molarity (M) is given as 2 M.
Step 2: Use the equation for molarity (M) to calculate the number of moles (n).
Molarity (M) = moles (n) / volume (V)
Rearranging the equation gives:
moles (n) = Molarity (M) x Volume (V)
Step 3: Plug in the values into the equation.
Molarity (M) = 2 M
Volume (V) = 5 L
moles (n) = 2 M x 5 L
Step 4: Perform the calculation.
moles (n) = 10 mol
Therefore, you would need 10 moles of H2SO4 to prepare a 2 M solution in 5 L of solvent.
