Molarity is only one of many ways to express concentration. Another is percent mass per volume or %(m/v). For example, vinegar usually contains about 5 %(m/v) acetic acid(5g acetic acid/100 mL vinegar). Calculate the molarity of acetic acid in a vinegar that is 5.5%(m/v)acetic acid. The molecular formula of acetic acid is C2H4O2.
15.0 moles of gas are in a 8.00 L tank at 21.0C. Calculate the difference in pressure between methane and an ideal gas under these conditions
a sample of argon gas is at a pressure of 1.24x10^4 kpa and a temperature of 24c in a rigid 25-L tank. How many moles of argon does this tank contain?
A plot of ln[AV] versus t (s) gives a straight line with a slope of -0.32s^-1. What is the value of the rate constant (k) for this reaction?
What is the maximum amount of O2 in grams that can be obtained from 2.00 x 102 g of nitroglycerin?
What is the temperature change If 84 joules of heat are added to a pure gold coin with a mass of fifteen grams? It is given that the Specific heat capacity of Au= 0.128
At 700.°C, the total pressure of the system is found to be 3.63 atm. If the equilibrium constant KP is 1.52, calculate the equilibrium partial pressures of CO2 and CO.
