To determine the number of moles in 0.000264 g of Li2HPO4, you first need to calculate the molar mass of Li2HPO4. The molar mass of Li2HPO4 is 115.79 g/mol. Next, you can use the formula n = m/M, where n is the number of moles, m is the mass in grams, and M is the molar mass. Plugging in the values, you get n = 0.000264 g / 115.79 g/mol ≈ 2.28 x 10^-6 moles of Li2HPO4.

Integration of log of sin x?
the integral of ln(sin(x)) is: -x*ln|1 - e2ix| + x*ln|sin(x)| + (i/2)*(x2 + Li2(e2ix)) + C where Li2 is the second order ploylogarithmic function.
What is the indefinite integral of 1 over the Li of x?
Better call it Li2(x).
What wavelength of light in nanometers must be absorbed to promote the electron in Li2 plus from n 1 to n 4?
Get Hertz with this formula. Z = 3 for Li.Hertz = (3.29 X 1015 s -1)*Z2*(1/Nf2 - 1/Ni2)We will reverse initial and final to avoid negatives.Hertz = (3.29 X 1015 s -1)(32)(1/12 - 1/42)Hertz = (9.87 X 1015)(15/16)= 9.25 X 1015 Hertz------------------------------Now, this formula.Wavelength = speed of light/HertzWavelength = 2.998 X 108 m/s/9.25 X 1015 Hertz= 3.24 X 10 -8 meters (109/1 meter)= 32.4 nanometers==============
