Answer:
361.0 milimoles of nickel chloride
Explanation:
Mili is a unit prefix that represents 1/1000 of the measured value. The multiplication of molarity with volume in liters gives the moles:
190.0mL = 0.190L * (1.90 moles / L) = 0.361 moles -Are moles of NiCl2.
Now, to convert moles to milimoles you must use 1 mole = 1000 milimoles thus:
0.361 moles * (1000 milimoles / 1 mole) =
