Chapter 1, Problem 1.4E

This is for practice. Do numbers 11 through 20

The figure below shows a dark globule of dusty gas. What do you think that globule would look like if you could see it from the other side?

a) A 555.0 g sample of liquid water is exposed to the light emitted by a nitrogen laser. Assuming that all the light energy converts to heat energy, moles of photons are required to raise the temperature of water by 3.00°C. The wavelength of the nitrogen laser light is 337 nm and specific heat of water is 4.184 . Enter only the number. J b) a container has the following mixture of gases: 28.5 % chlorine, 49.8 % neon and 21.7 % carbon dioxide by mass. The density of this mixture at 20.0°C and 801 mmHg is
