In many communities, water is fluoridated to prevent tooth decay. In the United States, for example, more than half of the population served by public water systems has access to water that is fluoridated at approximately 1 mg F− per liter. What is the molarity of F− in water if it contains 2.2 mg F− per liter? Express your answer using two significant figures.
Lead is a possible contaminant in public water systems. There are many reasons we should be concerned about this, but this may be especially concerning if the water is used for drinking. Removing all lead is not feasible, so many local governments must set an “acceptable” concentration for contaminants. The “acceptable” concentration of lead in public water for some states is 7.2 x 10^-7 M. If 10.00 mL of 1.00 M lead is poured down the sink, how many liters of water are required to make sure the concentration of lead is 7.1 x 10^-7 M, which is just below the acceptable level?
Determine the molarity of an AgNO3 aqueous solution that is 31.5% by mass given that its density is 1.284 g/mL.Provide your answer with 3 significant figures. ______________ M
