Question

how many moles of ammonia are in 0.25 l of a 5 m ammonia solution?1.25molspart bif this solution were diluted to 1 l, what would be the molarity of the resulting solution?m

Answer 1

To calculate the number of moles of ammonia in a given volume of a solution, use the formula Molarity = moles/volume. To find the molarity of a diluted solution, use the formula Molarity = Moles/volume. In this case, there are 1.25 moles of ammonia in 0.25 L of the 5 M ammonia solution, and if the solution were diluted to 1 L, the molarity of the resulting solution would be 1.25 M.

Step-by-step explanation:

To calculate the number of moles of ammonia in 0.25 L of a 5 M ammonia solution, you can use the formula:

Molarity = moles/volume

Rearranging the formula to solve for moles:

Moles = Molarity x Volume

So, Moles = 5 mol/L x 0.25 L = 1.25 moles

If this solution were diluted to 1 L, you can calculate the molarity of the resulting solution using the formula:

Molarity = Moles/volume

Moles = 1.25 moles (from before)

Volume = 1 L (after dilution)

Molarity = 1.25 moles/1 L = 1.25 M
