Find the amount of each acid needed to make 300 mL solution of a 1 mole solute to 100 mol solvent(water). Find HCL and CH3COOHFind the amout of NaOH needed to make 600 mL solution of a 1 mole solute to 100 mol solvent(water). Find NaOHGiven Info:HClConcentrated HCl (molarity 12.1) is 36% by volume, with a molar mass of 36.46g/mol.NaOHNaOH has a molar mass of 40.00g/molNote: NaOH has a highly exothermic heat ofsolution. Place the flask to about half its depth in water when making this solution. Do not proceed with the main experiment until the temperature of this solution has stabilized.CH3COOHConcentrated acetic acid has a density of 1.049g/mL, with a molar mass of 60.05g/mol.For the purposes of these calculations, you may assume that it is pure acetic acid.H2OWater has a molarity of 55.5 and a density of 1.000 g/mL.
The period 6 transition metals have greater densities than either the period 4 or 5 transition metals. An explanation concerns the 4f orbitals
Radiation with a 58.4 nm of wavelength interacts with a H 2 (hydrogen atom)and induces the ejection of an electron then determine the kinetic energy of the departing electron express your answer in eV?
A mixture of NaCl and NaBr has a mass of 2.08g and is found to contain 0.78 of Na.What is the Mass of NaBr in the mixture.
To determine the molar mass of an unknown protein, 1.00 mg was dissolved in 1.00 mL of water. At 25.0°C the osmotic pressure of this solution was found to be 1.47 × 10-3 atm.

Suppose the energy level of an electron with quantum number n was proportional to n instead of 1/n^2, E= -2.18 x 10^-19 J
If an ideal gas is expanded reversibly, the heat absorbed qrev, can be expressed by the differential dqrev = Cv dT + P dV, Where Cv is a constant (called heat capacity at constant volume). Show that dqrev is an inexact differential.
