What mass, in grams, of bromine gas (br2) is contained in a 15.7-liter tank at 24.6 degrees celsius and 0.986 atmospheres? show all of the work used to solve this problem.
use pv=nrt
r = 0.0821 l atm/mol k

PV = nRT

P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K

(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)

n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.
