Problem- A)- If 4.0L of a 4.7M SrCl2 solution is diluted to 50L , what is the molarity of the diluted solution?
B)-To what volume should you dilute 25mL of a 11.0M H2SO4 solution to obtain a 0.140M H2SO4 solution?
Explain each and every step in detail. I need proficient help in the above problems.
How many moles of o2 ca be produced by letting 12.00 moles of kclo3 react?
Problem- Assume that blood is mostly water. The Henry's law constant for N2 in water at 300 K is 86,000 atm. The hydrostatic pressure acting on a diver is 1 atm at the surface, and increases by approximately 1 atm for every 33 ft of depth.
Determine the osmotic pressure in atm of a non-volatile solution with a concentration of 0.710 M at a temperature of 34.2 ºC

Automobile airbags contain solid sodium azide, NaN3, that reacts to produce nitrogen gas when heated, thus inflating the bag. Calculate the value of w (work) for the following system if 13.9 g of NaN3 reacts completely at 1.00 atm and 22 °C.
A buffer is ready by mixing 200mL of 0.450 M HCL and 0.500 L of 0.400 M sodium acetate. Explain what is the pH Ka of CH3COOH = 1.8 x 10-5
A student dissolved 0.1319g of an unknown diprotic acid in 100mL of distilled water. The acid was then titrated with 0.1005M NaOH solution. The second equivalence point showed the sharpest change in pH, and so it was used to determine the molecula..
