Using the ideal gas law, determine the volume of a gas if 0.241 moles at 112 torr pressure has a temperature of 304 K. Calculate the number of moles of gas that has a volume of 450.0 ml at 23^{o} C and 745 torr. A sample of hydrogen gas...
In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a function of time. Once you have measurements at different times you can then plot these values and find the instantaneous rate of the reaction or the slope of the line. Pret...

Calculate the number of copper ions per gram of copper from the number of copper ions above and the mass of copper ions produced. The mass of the copper ions produced is equal to the mass loss of the anode. (The mass of the electrons is so small as to be negligible, so the mass of...
Find the mass of carbon dioxide that can be produced from 0.01 moles of calcium carbonate. A sample of CaCO_3 with a mass of 4.49 g is placed in 500.0 mL of 0.38 M HCl, forming CaCl_2, H_2O, and CO_2. What mass in grams of CO_2 was produced?
