Answer:

4.92 grams of sodium phosphate (Na₃PO₄) are required to make 125 milliliters of a 0.240 M.

Explanation:

Molarity is a measure of concentration that indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

Molarity=\frac{number of moles}{volume}

Molarity is expressed in units \frac{moles}{liter}.

In this case:

  • Molarity= 0.240 M
  • number of moles= ?
  • volume= 125 mL= 0.125 L

Replacing in the definition of molarity:

0.240 M=\frac{number of moles}{0.125 L}

Solving:

number of moles= 0.240 M*0.125 L

number of moles= 0.03 moles

Being the molar mass of sodium phosphate 164 g/mole, that is, the mass of one mole of the compound, you can calculate the mass of 0.03 moles using the following rule of three: if 1 mole of the compound has 164 grams, 0.03 moles contains how much mass?

mass=\frac{0.03 moles*164 grams}{1 mole}

mass= 4.92 grams

<u><em>4.92 grams of sodium phosphate (Na₃PO₄) are required to make 125 milliliters of a 0.240 M.</em></u>

Draw the product you expect from the reaction of (s)-3-iodohexane with ch3co2-. be sure to show stereochemistry.
Rasek [7]

This will give substituted product which will be by SN2 mechanism

so here we will get product with inverted geometry

In SN2 mechanism the nucleophile attacks from back side and we always get product with inverted geometry

This is known as Walden inversion.
