Pioneer Energy Solutions
Chemistry Problems?
1) The space probe Pioneer 11 was launched April 5, 1973, and reached Jupiter in December 1974, traveling a distance of 944 million km. How long (in minutes) did it take an electromagnetic signal to travel to earth from Pioneer 11 when it was near Jupiter?
2) What is the energy (in J) of a photon corresponding to microwave radiation of frequency 1.258 x 1010 /s?
3) Calculate the longest wavelength (in nm) of the electromagnetic radiation emitted by the hydrogen atom in undergoing a transition from the n=6 level.
4) What is the final concentration if 41.31 mL of a 2.574 M glucose solution is diluted to a volume of 600.0 mL?
Sorry there is so many, I just am having trouble with these problems
I worked them out completely following examples I found and I was off on each answer by anywhere from 50 to 100 off from what the answer is
So, what are your problems with the questions? How far did you come? Someone will surely help you, but this is no homework service
