12.00 g of an unknown nonelectrolyte in enough water to make 2.00 L of solution. The osmotic pressure of this solution is 0.750 atm at 25.0°C. What is the molecular weight of the unknown solute (R = 0.08206 L•atm/K•mol)
What is the formula that relates the temperature change obsereved in a substance with the energy released or abosrbed? when you measure a temperature rise during a chemical reaction, is the reaction endothermic or exothermic?
Rearrange the equation discovered by Balmer to solve for n2 (get n2 by itself): 1/? = R(1/2^2 - 1/n^2) where: ? = is the wavelength of the photon (E=hc/?) R = Rydberg's constant (1.0974x10^7 m^-1) n1 and n2 are integers where n2 > n1.
