The ideal gas equation is pv=nrt where p is pressure, v is volume, n is the number of moles, r is a constant, and t is temperature. you are told that a sample of gas has a pressure of p = 859 torr , a volume of v = 8960 ml , and a temperature of t = 304 k . if you use r = 8.206×10−2 l⋅atm/(k⋅mol) , which of the following conversions would be necessary before you could find the number of moles of gas, n, in this sample?

Take a look to R, where the units are L . atm/K . mol.. your pressure is in Torr...so make the conversion to atm. (760 Torr is 1 atm) and then take the volume... as you have mL, remember that R is with L, so convert mL to L by making the division /1000. Pressure and volume are those you have to convert

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

indium, and thallium have three electrons i think
