How much (in g) of CO2 is dissolved in 0.5 L of a drink which was produced under CO2 pressure of 500 kPa?

2.0 g of a substance in 12 mL of a solvent is extracted with three aliquots of 10 mL of anextracting solvent. How much of the substance by mass was extracted out of the originalsolvent? (Assume K=2)

Calculate the osmotic pressure in torr of a 0.073 M solution of A,X2 in water if the temperature is 22 degrees C. Assume A,X2 completely dissolves. R = 0.08206 Latm mol K

Q/ Mohr's method uses the potassium chromate indicator and this indicator makes the equivalent point not identical to the end point. A sample weighing 5.592 g of BaCl2 is dissolved in 500 mL of water. Calculate the percentage of chloride in the sample when 25 mL of the sample is titrated and requires 33.47 mL of 0.1098 N AGNO. SOLUTION:

The solubility of CO2 in water is a function of pressure.Calculate the concentration of CO2 in water when ???2 = 2.5 × 10−4 bar

The state of California has set an upper limit of 50. ppb of chromium (by mass) in drinking water. Suppose you drink the recommended eight 8-ounce glasses of water (1.9 kg of water) with this concentration in one day. How much chromium did you ingest that day?

The freezing point of water, H2O, is 0.000 °C at 1 atmosphere. Kf(water) = 1.86 °C/mIn a laboratory experiment, students synthesized a new compound and found that when 11.94 grams of the compound were dissolved in 217.1 grams of water, the solution began to freeze at -1.702 °C. The compound was also found to be nonvolatile and a non-electrolyte.What is the molecular weight they determined for this compound?
