Calculate the volume of 1.78M sulfuric acid that would be needed to neutralize 62.4 mL of a 2.09 M aqueous ammonia solution. The equation for the reaction is H2SO4(aq) + 2 NH3(aq) ---> 2 NH4(aq)+ SO4 ^-2 (aq)
Assume there are two lakes containing trout and the weights of the trout in each lake are normally distributed. The distribution of trout weight in Lake A has a mean of 18 ounces with a standard deviation of 2 ounces. The distribution of trout weight in Lake B has a mean of 19...
Suppose a tire manufacturer wants to set a mileage guarantee on its new XB 70 tire. Life tests revealed that the mean mileage is 47,900 miles and the standard deviation is 2,050. The manufacturer wants to set the guaranteed mileage so that no more than five percent of the tire...
