A (pretty sure) PLEASE MAKE ME BRAINLIEST
Ideal gas law PV = nRT or PM = dRt ( M is molecular mass of gas ) and d is gas density
where m/ M ( m is mass of gas sample )
m = dRT / P ( 2.78 g/L ) ( 0.082 L atm/ K mole )( 310K ) / 1.2 atm =
58.9 g/mol
gas must be butane ( C4H10) has molecular mass = 58.9 g/mol
DNA and rna!!!!! Hope it helps
Answer:
first ionization energy is the amount of energy required to remove an electron from isolated gaseous atom
so when atomic no increase across aperiod the ionization energy become lower
it's my opinion am not sure ok
