What is the concentration (M) of a NaCL solution prepared by dissolving 9,3g of Nacl in sufficient water give 350ml of solution?.Any idea???

molarity= molesNaCl/volumeinliters

= 9.3/58*.350

To find the concentration (M) of a NaCl solution, you need to know the amount of NaCl (in moles) and the volume of the solution (in liters).

Step 1: Convert the mass of NaCl (9.3g) to moles using the molar mass of NaCl.

The molar mass of NaCl is the sum of the atomic masses of sodium (Na) and chlorine (Cl),
Molar mass of Na = 22.99 g/mol
Molar mass of Cl = 35.45 g/mol

So, the molar mass of NaCl = 22.99 + 35.45 = 58.44 g/mol

To convert grams to moles of NaCl, divide the given mass (9.3g) by the molar mass (58.44g/mol):
9.3g / 58.44g/mol = 0.159 moles of NaCl

Step 2: Convert the volume of the solution (350ml) to liters.

To convert milliliters to liters, divide the given volume (350ml) by 1000:
350ml / 1000 = 0.35 liters

Step 3: Calculate the concentration (M) using the formula:

Concentration (M) = moles of solute / volume of solution (in liters)

Substitute the values into the formula:
Concentration (M) = 0.159 moles / 0.35 liters = 0.454 M

Therefore, the concentration of the NaCl solution prepared by dissolving 9.3g of NaCl in sufficient water to give 350ml of solution is 0.454 M.

To find the concentration (M) of a solution, we need to know the number of moles of solute (in this case, NaCl) and the volume of the solution.

Step 1: Calculate the number of moles of NaCl:
We can use the formula: moles = mass / molar mass.

The molar mass of NaCl is equal to the sum of the atomic masses of Na (22.99 g/mol) and Cl (35.45 g/mol), which is 58.44 g/mol.

moles = 9.3 g / 58.44 g/mol
moles ≈ 0.159 mol

Step 2: Calculate the concentration (M):
The concentration is given by the formula: M = moles / volume (in liters).

Since the volume is given in milliliters (ml), we need to convert it to liters by dividing by 1000 (1 L = 1000 mL).

volume = 350 ml / 1000
volume = 0.350 L

M = 0.159 mol / 0.350 L
M ≈ 0.454 M

Therefore, the concentration of the NaCl solution prepared by dissolving 9.3g of NaCl in sufficient water to give a 350 ml solution is approximately 0.454 M.
