Carl's chemistry teacher asked him to make a 1 m sodium chloride solution. carl measured 58.44 grams nacl, added it to a volumetric flask, and then added enough water to make a 1 liter solution. carl's lab partner told him that he had made the 1 m solution incorrectly. how would you respond to her comment regarding carl's lab technique?

After measuring the solute, Carl should first dissolve the solid in a small amount of DI water before diluting to the total volume.

Explanation:

To ensure that all the solute dissolves in the solution, first dissolve the solid in less than the total volume of solution needed.

Molarity is the moles of solute dissolved in 1 liter of the solution.

1 M NaCl solution is 1 moles of NaCl in 1 L of the solution.

Here the solute is NaCl and its molar mass is 58.44 g/mol. So measuring out 58.44 g of NaCl gives 1 moles of NaCl. Carl then added water to bring the volume up to 1 Liter. Carl's lab technique is correct.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
