Calculate the amount (mL) of Compound A needed to give 12 mmol. MW of Compound A: 32.04 g/mol Density of Compound A: 0.79 g/mL
When a solution is formed by mixing solute B with solvent A, the vapor pressure of A falls to 80% of its value for the pure solvent. What is the composition of the solution
A student sets up two reactions. Reaction 1 uses 0.170 mole/L of reactant, and Reaction 2 uses 0.460 mole/L of reactant. How many times faster is Reaction 2 compared to Reaction 1
You have 100 moles of solvent (not water). You have determined that 100g of dissolved sucrose incrases its boiling point temperature by 10C. For 100 moles of the pure solvent, how much mass (in grams) of salt
Calculate the magnitude of the current in amperes if the number of moles of hydrogen gas produced is 4.80×10-4 moles.
When 1 mol of HF is added to 1kg of water, the freezing point decreases by 1.9 C, but when 1 mol of HBr is added, the freezing point decreases by 3.7 C. Which is more highly separated into ions, HF or HBr
The kinetic energy of the ejected electron is given by 1/2 mv2= h v -?. where m and v are the mass and velocity of the electron
A student makes a voltaic cell using zinc solid metal, zinc chloride, tin solid metal and tin chloride, and of course a salt bridge filled with KCl. What voltage would you expect from this cell at room temperature and 1M solutions
Use the molar volume of a gas at STP to calculate the density (in g/L ) of carbon monoxide gas at STP.
The concentration of phosphoric acid in Coke is approximately 106.0 mg/mL. Assuming phosphoric acid is the only acid in Coke, calculate the pH of a 355 mL can of Coke.

From the Bohr model of the hydrogen atom, what can we conclude about the energy required to excite an electron
In all parts: assume the the speed of sound in air is 339 m/s. Suppose a ship's foghorn is sounded toward an iceberg, and an echo is heard 4.33 s later. What is the distance from the ship to the iceberg. Suppose the lab floor is 3.12 m beneath the..
