Based on the following water composition, determine the alkalinity, total hardness and carbonate hardness in units of mg/L CaCO3. (Note: you may want to refer back to our notes on units and recall that CaCO3 has 2 eq/mol.) Ion Conc. (mg/L) MW (g/mol) Equiv. Conc. (meq/l) Conc (mg/L as CaCO3) Ca2+ 30 40 Mg2+ 10 24.3 Na+ 12 23 CI- 11 35.5 Alk (HCO3) 110 61

QUESTION 16 Calculate the freezing point. in degrees Celsius, of a solution containing 58.5 grams of CHCI3 (molar mass-119.38 g/mol) and 644.4 grams of eucalyptol C10H180 (molar mass-154.24 g/mol), a fragrant substance found in the leaves of eucalyptus trees. The molal-freezing point depression constant for C10H180 is 4.68°C/m and pure C10H180 freezes at -63.5°Cc. Express your answer to ene decimal place.

The density of carbon tetrachloride (CC14) is used as a reference density at a specific condition to measure the specific gravity of the liquid substance Select one: O True O False

At a certain temperature and pressure, a 1.00 mol sample of argon gas is pumped into a 22.4 L rigid box that already contains 1.00 mol of nitrogen gas.  We would expect the argon gas to: Group of answer choices decrease the total gas pressure in the box by a factor of 2 occupy the entire 22.4 L volume of the box. increase the total gas pressure in the box by a factor of less than 2. spread out into the box, but the actual volume occupied but he gas cannot be known without pressure information. occupy only 11.2 L of the box.

Find the molar concentration in mol litre-1 of a solution if 46 kg of acompound (relative mass = 110) is present in a solution whose volume is36 litres.
