Three significant figures
With the correct unit
1) 50.0 mL of a solution contains 0.0285 moles of AgNO3. Calculates the Molarity for a solution
2) A sample of 0.00116 moles of NaCl is placed in a volumetric flask and water is added to dissolve it up to 25.0 mL. Calculates the Molarity of the solution.
3) Determines the molarity for a NaCl solution, the volume of which is 0.01006 L and the amount of moles is 0.00164 moles.
4) Dissolves 0.018 moles of H2SO4 in enough water to have 0.100 L solution. What is H2SO4 Molarity in solution?
An aqueous solution contains 12.5% NaCl by mass. What mass of water (in grams)is contained in 2.5L of the vapor above this solution at 55 celcius? the vaor pressure of pure water at 55 celcius is 118 torr.
A current of 11.3 A is applied to 1.25 L of a solution of 0.552 M HBr converting some of the H+ to H2(g), which bubbles out of solution. What is the pH of the solution after 73 minutes?

The inventor proposed the revolutionary design of the new engine based on the heat stored in the ocean. The inventor plan is to mount it on a boat in San Francisco and set off on a journey across the Pacific Ocean.
Molecule X has an absorbance of 0.287 at 247nm when a 7.67 x 10^-5 M solution is measured in a 2.25 cm cell. What is the molar absorptivity of X
On or after the Bohr model of the hydrogen atom we can conclude that the energy necessary to excite an electron from n = 2 to n = 3 is the energy to excite an electron from n = 3 to n = 4.
Equilibrium constant for the cell reaction is (A)100 .32/0.0591 (B)100.32/0.0295 (C) 100.26/0.0295 (D) e0.32/0.295
