Chemical analysis of olivine (orthorhombic, Z=4) shows that it contains 40.99 wt % SiO2, 50.00 wt % MgO, 8.99 wt % FeO and a trace of MnO. The measured cell dimensions are a=4.76A, b=10.21A, c=5.99A. Determine the density of this member of the olivine family.
It is determined that 3.75 x 10^-4g of a contaminant is present in 3750g of a particular solution. What is the concentration of contaminant in ppm (m/m)?
Some AgCl(s) has been placed in a beaker of water. After some time, the solubility of Ag+ and Cl- was measured to be 2.5 x 10-5 M. Determine whether the system has reached equilibrium.
About 30% of crude oil is processed eventually into automobile gasoline. As petroleum prices rise and resources dwindle, alternatives must be found. However, automobile engines can be tuned so that they will run on simple alcohols. Methanol, and e..
