Question- How can I tell if by UV/VI graphs that a solution could have a ph of 5, 7 or 12? Do I look at the abosorbance because the wavelength of all of them are 511 nm
Please illustrate work if possible thanks

canadian 10cent and 25cent coins are made of pure nickelwhich has a density of 8.902 gcm3. suppose each dimeweighs 2.14
Sodium has a density of 0.968g/cm3 and crystallizes with the body-centered cubic unit cell. Calculate the radius of a sodium atom.
The mole fraction of benzene in the solution is 0.590. Assumeing ideal behavior, calculate the mole fraction of toluene in the vapor above the solution.
a calculator to calculate the average and standard deviation for x1 through x12. i know how to find the average but i dont understand how to findthe standard deviation.
A buffer contains significant amounts of a weak acid and a salt containing its conjugate base. The acid consumes any added base, and the base consumes any added acid. In this way, a buffer resists pH change. Strong acids, strong bases, two bases, ..
