Chemistry
What volume of 0.500 M hydrochloric acid is required to exactly neutralize 40.00 mL 0.150 M NaOH?

Chemistry
Never mind I figured it out!

Chemistry
The solubility of Mg(OH)2 in a particular buffer solution is 0.63g/L .What must be the pH of the buffer solution? I am unsure of where to start since this is the first solubility problem that I've done that has included the density.

Chemistry
A 100.0 ml sample of .50 M HCl (aq) is titrated with a .10 M NaOH. What volume of the NaOH solution is required to reach the endpoint of the titration?

Chemistry
If 62.7 ml of .208M HCL is needed to needed to neutralize a solution of Ca(OH)2, how many grams of Ca(OH)2 must be in the solution?

Math
Rubber stripping for a trailer needs to be exactly 2.93 meters long. About how many of these pieces can be cut from a 12-meter length of rubber stripping? Estimate by using compatible numbers.

Physics
A light spring of constant k = 158 N/m rests vertically on the bottom of a large beaker of water (Fig. P9.34a). A 5.55 kg block of wood (density = 650 kg/m3) is connected to the spring and the mass-spring system is allowed to come to static equilibrium (Fig. P9.34b). What is t...
