Take a hypothetical sample of exactly 100 grams of the solution.
(16g urea) / (60.06 g urea/mol) = 0.2664 mol urea
((100 g total) - (16g urea)) = 84.0 g H2O = 0.0840 kg H2O
(0.2664 mol) /0.0840 (kg) = 3.17143mol/kg = 3.18m urea
<span>Answer: D. They all have the same number of electrons in the electron cloud</span>
You don’t have any answer chooses listed but i’ll say F isn’t a molecule because it stands for fluorine which happens to be an element that only has one atom when a molecule is supposed to have two or more atoms.
