Which of the following are acceptable ways to make one liter of 1 M NaCl?
RSB [31]

Initially, weigh the correct amount of NaCl calculated from the formula.

Number of moles  =\frac{Given mass in g}{Molar mass}

As 1 mole of NaCl is given and molar mass of NaCl is 58.44 g/mol, then

1 mole of NaCl= \frac{Given mass in g}{58.44 g/mol}

Mass of NaCl in g = {58.44 g}

Thus,

1 mole of NaCl = 58.44 g.

Now, the weighed amount of NaCl i.e. 58.44 g is added to a 1 liter container and then add small amount of water in the container to dissolve the salt. After that, fill the container with distilled water to the graduation mark or until the total volume reaches 1 liter.

Thus, option (c) is correct i.e. first put one mole of salt in the container then add the water with stirring till the total volume reaches 1 liter.

If 10.0 mL of the solution on the right are withdrawn from the 100 mL beaker and diluted again in a similar manner, what is the
maks197457 [2]

Answer: 0.050 M NaCl

Explanation:

So the original solution is diluted from a total volume of 10.0 mL to 100.0 mL.

The M represents molarity which is moles of NaCl divided by the total solution volume in liters.

So if our original volume were to be increased by a factor of 10 then the denominator would be changed.

Here is a mathematical illustration:

5/10 = .5

5/100 = .05
