A chemist prepares a solution..

A chemist prepares a solution of magnesium fluoride (MgF) by measuring out 0.00973 umol of magnesium fluoride into a 100. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mmol/L of the chemist's magnesium fluoride solution. Be sure your answer has the correct number of significant digits. mmol x 6 ?

Answer 1

1 mol = 103 mmol = 106 umo 103 mmol = 100 umor I mmol = 103 umol 103 eumol 3 mmol 103 umo, 1 mmol v= 100 ml v= 1000 litre 1000 v = 0.100 litre mol concentration = volume (litre) 0.00973 umol 0.100 litre 0.0973 umol x (1) L = 0.0973 Amol x 1 mmol 1 ( 103 umol/ 2 0.0973 103 mmol/ = 0.0973 x 10 -3 mmol/ = 9.73 x 10-5 mmol
