What mass of KCl (MM = 74.55 g/mol) is required to make 600 mL of a 0.175 M solution

How many moles do you need? That will be

M x L = ??
Then ??moles = grams/molar mass. Solve for grams.

To find the mass of KCl required to make a 0.175 M solution in 600 mL volume, we can follow these steps:

1. Convert the given volume from milliliters (mL) to liters (L):
600 mL = 600/1000 = 0.6 L

2. Use the formula for molarity to calculate the number of moles of KCl required:
Molarity (M) = Moles (mol) / Volume (L)

Rearrange the formula to find the number of moles:
Moles (mol) = Molarity (M) x Volume (L)

Moles (mol) = 0.175 M x 0.6 L
Moles (mol) = 0.105 mol

3. Calculate the mass of KCl using the molar mass:
Mass (g) = Moles (mol) x Molar Mass (g/mol)

Mass (g) = 0.105 mol x 74.55 g/mol
Mass (g) = 7.83825 g

So, approximately 7.84 grams of KCl is required to make a 600 mL solution with a molarity of 0.175 M.
