Achemist prepares a solution of sodium nitrate by weighing out 122g of sodium nitrate into a 250ml volumetric flask and filling the flask to the mark with water. calculate the concentration in mol/l of the chemist's sodium nitrate solution. be sure your answer has the correct number of significant digits.

when the pressure is increased, there will be a shift to the reactants side. decreasing the volume will increase pressure. when you decrease the volume, the gaseous species get more tightly packed of the concentrations of gaseous species increase.

le chatelier's principle says that the system wants to undo this concentration increase so it can decrease pressure.

since the reactants only have 1 mol of gas (only pcl5) and the products have 2 mol of gas (both pcl3 and cl2), it shifts to reactants to decrease concentration, thereby lowering the pressure

explanation:

nacl - sodium chloride
