Apharmacist has a prescription for 30 ml of an eye drop that is to contain benzalkonium chloride 1: 750 as a preservative. on the shelf the pharmacist finds 17% benzalkonium chloride. using a dropper that delivers 25 drops/ml, how many drops will be required to prepare this compounded formula? (answer must be numeric; no units or commas; round the final answer to the nearest whole number.)

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
