To make a 3.50 M solution, how many moles of solute will be needed if 11 liters of solution are required?

To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.

Explanation:

Molarity is defined as a concentration unit that indicates the number of moles of solute per liter of solution. That is, it indicates the number of moles of solute that are dissolved in a given volume. Then, the molarity is calculated by dividing the moles of the solute by the liters (volume) of the solution:

Molarity is expressed in units ().

So, knowing the definition of molarity, you can apply a rule of three as follows: if by the definition of molarity in 1 L of solution there are 3.5 moles of solute, in 11 L of solution how many moles of solute are there?

moles=38.5

To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.

The number of moles is 38.5 moles

Explanation:

Given:

Concentration of the solution = 3.5 M

Volume of solution = 11 L

Question: How many moles of solute, nsol = ?

The molarity is the number of moles of the solute divided by the volume of the solution, in this case:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
