An exercise in lab requires you to make 500 mL of 2.3M beryllium sulfide solution. How many moles of beryllium sulfide will you need 


Expert Answer

Step 1


Volume of the solution = 500ml

Molarity of the solution = 2.3M

Step 2

Molarity is the number of moles in the unit volume of solution

no of moles
volume of solution (in litres)

Image Transcriptionclose

no of moles Molarity volume of solution (in litres)

Step 3

Since the molarity of the solution is given alon...

rearranging the equation
no of moles molarity x volume(in litres)

Image Transcriptionclose

rearranging the equation no of moles molarity x volume(in litres)
