What is the molar concentration (in moles/L) of a solution made with 3.744 g of Mg(NO3)2 dissolved in enough water to make 50.0
Annette [7]

Answer:

The molar concentration of a solution made with 3.744 g of Mg(NO₃)₂ dissolved in enough water to make 50.0 mL of solution is 0.5 \frac{moles}{L}

Explanation:

Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain 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}

In this case:

  • Mg: 24.3 g/mole
  • N: 14 g/mole
  • O: 16 g/mole

So, the molar mass of Mg(NO₃)₂ is:

Mg(NO₃)₂= 24.3 g/mole + 2*(14 g/mole + 3*16 g/mole)= 148.3 g/mole

So, if you have 3.744 g of Mg(NO₃)₂, you can apply the following rule of three: if 148.3 grams of Mg(NO₃)₂ are present in 1 mole, 3.744 grams in how many moles are present?

moles=\frac{3.744 grams*1mole}{148.3 grams}

moles= 0.025

Then you have:

  • number of moles=0.025
  • volume= 50 mL= 0.05 L (being 1,000 mL= 1 L)

Replacing in the definition of molarity:

molarity=\frac{0.025 moles}{0.05 L}

you get:

molarity=0.5 \frac{moles}{L}

<u><em>The molar concentration of a solution made with 3.744 g of Mg(NO₃)₂ dissolved in enough water to make 50.0 mL of solution is </em></u>0.5 \frac{moles}{L}<u><em></em></u>

Drag the tiles to the correct boxes. Not all tiles will be used. The oxidation number of oxygen is -2, and that of chlorine is -
Evgen [1.6K]

<u>Answer:</u>

<em>That oxidation number of chlorine is -1 while that of oxygen is -2</em>

<u>Explanation:</u>

When it comes to manganese chloride to stabilize the chlorine Ion. Two manganese ions shall be required. Hence the formula for the compound becomes M_nCl_2 while the formula for manganese (iv) chloride will be M_nCl_4 similarly.

When oxygen and magnesium oxide is considered the Two ions of Manganese will satisfy to ions of oxygen. Which cancels and becomes M_nO while for manganese (iv) oxide  the formula becomes M_nO_2.
