Based upon the molarities of the standardized hcl and standardized naoh, and the volumes of each added to analyze the antacid samples, calculate the millimoles of hcl needed to neutralize the tablet per milligram of sample.

average molarity hcl: 0.4548
average molarity nacl: 0.1048
vol hcl(ml): 14.10
vol nacl(ml): 14.60
mass tablet: 1.333g
mass antacid: 0.613

How to convert a density of 0.791g/cm3 to lb/ft3

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size

Achemist 16 drop copper metal from copper chloride solution. the chemist place is 0.50 g of aluminum foil in a solution containing 0.75 g of copper (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction?
