Compute the change in temperature when 1.8 g of sodium chloride is dissolved in 300.0 mL of water initially at 20C. The heat capacity of water is 4.184 J/mL/K. Neglect the heat capacity of the NaCl.Species fH (kJ/mol) NaCl(aq) -407.3 NaCl(s) -411.2
Calculate the number of moles of Cl atoms in 1.20×1024 of magnesium chloride, MgCl2.
A solution is prepared by dissolving 179 g sucrose (C12H22O11) in enough water to produce 1.15 L solution. What is the molarity of this solution?
Tank full of water (H2O)is open at the top with the hole near the bottom the area of which is 0.25 m^2 and the cross section area of the tank =1 m^2 determine what is volumetric flow rate out of the hole.
A bomb calorimeter whose components have a heat capacity of 6.66 kJ/°C is filled with 913 g of water. (The amount of water is not constant from experiment to experiment.
A solution is prepared by mixing 63.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
