Alab technician needs to create 570.0 milliliters of a 2.00 m solution of magnesium chloride (mgcl2).  to make this solution, how many grams of magnesium chloride does the technician need? refer to the periodic table for .  express your answer to three significant figures. the required mass is  grams.

109 for just did it 5/5 correct (Three significant figures)

This question needs to use the molarity equation, , where M is molarity, n is number of moles and V is the volume. With this equation we can find the number of moles. The volume of 570ml should be converted to L for correct units.

Multiply the number of moles by the molecular mass of which is 95.21 g/mol to get the mass.
