three containers of equal volume are filled with Xenon, Carbon Dioxide and air ( 78% N2, 21% O2, 1%Ar). (all containers are at the same P and T). Which container has the most "gas particles"? which has the least? (in the context a gases, we often use "molecules" to mean generic gas particles that is, it includes single atoms for noble gases). which has the most mass? which has the least? which has the most number of atoms? which has the least ? which has highest density? which has the least? Do the most atoms always correspond to most mass?
Calculate the empirical formula and then determine the molecular formula of this compound using the given molar mass. b) Draw three lewis structures for molecule that satisfies the octet rule for each atom.
The molecular formula of glycine (an amino acid) is NH2CH2COOH, the molecular mass is 75.07grams/mole. If 10 glycines are joined together by a dehydration reaction to make a polypeptide, what would the molecular mass of the polypeptide equal.
