Calculate the amount (mL) needed of a 4.0 M phenylmagnesium chloride in THF solution to give 1.5 equivalents based on the amount of starting material used. Starting material needed: 0.58 mmol? mL of 4.0 M phenylmagnesium chloride in THF (HINT: remember to convert to moles; think about what the units of molarity are; remember significant digits, 4.0 has two significant digits)
