A student takes a measured volume of 3.00 M HCl to prepare a 50.0 mL sample of 1.80 M HCl. What volume of 3.00 M HCl did the student use to make the sample?

anonymous · Answer

@iPwnBunnies  helppp please

ipwnbunnies · Answer

$$M_1 V_1 = M_2 V_2$$
Where 'M' is the molarity and 'V' is the volume in Liters.

anonymous · Answer

can you lead me through  it

ipwnbunnies · Answer

Well, the student wants 50 mL of a 1.80 molarity solution. But he has a 3.0 molarity solution. Let V1 = 50 mL, M1 = 1.8, M2 = 3.0, and solve for V2. That would be in milliliters.

i have one more question i need help checking can you help i'll give a medal or something.

anonymous · Answer

The molar solubility of lead(II) phosphate (Pb3(PO4)2) is 7.9 x 10-43   M. Calculate the solubility product constant (Ksp) of lead(II) phosphate.
