1. A standard nitric acid solution is prepared using 0.425 g of sodium carbonate, Na2CO3. Find the molarity of the acid if 33.25 mL are required to reach a permanent endpoint. 2 HNO3(aq) + Na₂CO3 (s) → 2 NaNO3 (aq) + H₂O(1) + CO₂(g) 2. A 10.0-mL sample of household ammonia solution required 27.50 mL of 0.241 M HNO3 for neutralization. Calculate (a) the molar concentration of the ammonia and (b) the mass/mass percent concentration of ammonia (17.04 g/mol), given a solution density of 0.985 g/mL. HNO3(aq) + NH3 (aq) → NH4NO3(aq) (a). (b). A 10.0 mL sample of calcium hydroxide solution required 26.85 mL of 0.225 M hydrochloric acid for neutralization. Calculate (a) the molar concentration of the base. 2 HCl(aq) + Ca(OH)2 (aq) → CaCl₂(aq) + 2 H₂O(1)

A soft drink contains an unknown mass of citric acid, C3H5O(COOH)3. It requires 6.42 mL of 9.580 × 10−2-M NaOH to neutralize the citric acid in 10.0 mL of the soft drink. C3H5O(COOH)3(aq) + 3 NaOH(aq) → Na3C3H5O(COO)3(aq) + 3 H2O(ℓ) Determine which step in these calculations for the mass of citric acid in 1 mL soft drink is incorrect? Why? n (NaOH) = (6.42 mL)(1L/1000 mL)(9.580 × 10−2 mol/L) n (citric acid) = (6.15 × 10−4 mol NaOH) × (3 mol citric acid/1 mol NaOH) m (citric acid in sample) = (1.85 × 10−3 mol citric acid) × (192.12 g/mol citric acid) m (citric acid in 1 mL soft drink) = (0.354 g citric acid)/(10 mL soft drink) Determine the correct result.

Explain completely.
Magnesium sulfate (MgSO4) has a solubility of 38.9 g/ 100 g H2O at 30C. A solution is prepared by adding 9.50 g of MgSO4 to 25.0 g of water at 40C. A homogeneous mixture is obtained. Is the solution saturated, unsaturated, or supersaturated? One gram of magnesium sulfate is added to the solution cooled to 30C. Would you expect some of the MgSO4 to precipitate? If so, how much? If not, how much more MgSO4 can be added before precipitation takes place?

Without consulting your textbook, list and explain the main postulates of the kinetic molecular theory for gases. How do these postulates help us account for the following bulk properties of a gas: the pressure of the gas and why the pressure of the gas increases with increased temperature; the fact that a gas tills its entire container; and the fact that the volume of a given sample of gas increases as its temperature is increased.
A student wants to prepare 1.00 L of a 1.00-M solution of NaOH (molar mass = 40.00 g/mol). If solid NaOH is available, how would the student prepare this solution?
