Calculate the osmotic pressure (in atm) of 8 L of an aqueous solution with a concentration of 0.1073 M at 29.1°C, if the solute concerned is totally dissociated in three ions ( i.e. it could be MgCl 2
What volume (in mL) of a 0.7643 M solution of CaCl2 contains 1.766 g of the solute?
Thanks everybody!-Solute is usually so cant u just find wat the solvent is and subtract from total.
Im having trouble with the following question as I missed it during class:
Of Sn 2+, Ag +, and/or Zn 2+, which could be reduced by Cu?
A.Ag+B.Sn2+C.Zn2+D.All of them could be reduced by Cu.E.Two of t
What volume (in mL) of a 0.7643 M solution of CaCl2 contains 1.766 g of the solute?
Can anybody solve this?-First calculate how many mole CaCl2 you have
Ca = 40,078 g/mol x 1 = 40,078
Cl = 35,453 g/
If the heat of combustion for a specific compound is -1080.0 kJ/mol and its molar mass is 89.83 g/mol, how many grams of this compound must you burn to release 294.20 kJ of heat?
I have tried doing t

same temperature
When 0.1009 g of sodium cyanide is dissolved in solution, it takes 19.22 mL of a potassium permanganate solution to reach the end point of the titration. Using the balanced chemical equation provided,
Suppose that 5.8 L of methane at a pressure
of 680 Torr is transferred to a vessel of volume
4.8 L. What is the final pressure of methane if the change occurs at constant temperature?
Answer in units
Determine the limiting reactant if 50.0 g of
NO are mixed with 30.0 g of O2 according to
the reaction
2NO + O2 --> 2NO2
1. O2
2. NO
3. There is not a limiting reactant.
4. NO2
5. It is impossible to

Arent bases compounds that produce hydroxide ions when dissolved in water? But there ARE no hydroxide ions in NaHCO3? I tried googling it, but I didnt understand the explanations.. Can someone explain
