Achemist prepares a solution of magnesium fluoride mgf2 by measuring out 0.00598μmol of magnesium fluoride into a 50.ml volumetric flask and filling the flask to the mark with water. calculate the concentration in /μmoll of the chemist's magnesium fluoride solution. round your answer to 2 significant digits.

0,12 μmol/L of MgF₂

Explanation:

Preparation of solutions is a common work in chemist's life.

In this porblem says that you measure 0,00598 μmol of MgF₂ in 50,0 mL of water and you must calculate concentration in  μmol/L

You have 0,00598 μmol but not Liters.

To obtain liters you sholud convert mL to L, knowing 1000mL are 1 L, thus:

50,0 mL (1L/1000mL) = 0,05 L of water.

Thus, concentration in  μmol/L is:

0,00598 μmol / 0,05 L = 0,12 μmol/L -The problem request answer with two significant digits-

I hope it helps!
