An aqueous solution is 22.0% by mass silver nitrate, AgNO3, and has a density of 1.22 g/mL. What is the molarity of silver nitrate in the solution?
Cyanogen is a gas which contains 46.2 % C and 53.8 % N by mass. At a temperature of 25oC and a pressure of 750 mmHg, 1.50 g of cyanogen occupies 0.714 L.
if the initial water level in the graduated cylinder is 21.2 ml and the level rises to 27.7 ml after the object is placed in the cylinder, what is the volume of the object?
Explain how these products are produced by showing the mecahnism involved. (draw).
What volume in L is occupied by 19.62 g of methane, CH4 (MM = 16.04 g/mol) at 23 °C and 1.34 atm?
Determine the partial pressure and total pressure of each gas in the vessel and process of reaction runs until eighty five of the Oxygen is used and the vessel get cooled to its starting or initial temperature.
Calculate ΔG for the reaction if the partial pressures of the initial mixture are PPCl5 = 0.0029 atm, PPCl3 = 0.27 atm, and PCl2 = 0.40 atm PCl5(g)--> PCl3(g) + Cl2(g)
To determine the number of molecules present in air using the ideal gas law and Avogadro's number - how many molecules of each type of gas are present in 1.0 L of air at STP?
What is ozone and how it works as a protective molecule for our environment? What are the effects of CFCs on the ozone layer.
Suppose you have a sample of sodium weighing 11.62 g. How many atoms of sodium are present in the sample?
How much heat (in kJ) is required to warm 16.0g of ice, initially at -11.0 C, to steam at 112.0 C? The heat capacity of ice is 2.09 J/g*C and that of steam is 2.01 J/g*C.
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
A 1-L flask is filled with 1.45 g of argon at 25^0C. A sample of ethane vapor is added to the same flask until the total pressure is 1.25 atm.what is the partial pressure of argon in the flask?
