Measure which mass? I recommend editing the question so that I can answer it and get more points >:)
Alcohols always contain the Hydroxyl functional group (-O H) - (or just hydroxyl group), which is an oxygen atom bound by a covalent (with shared electron pairs) bound to a hydrogen atom.
Answer:
The most abundant gas in the atmosphere is nitrogen, with oxygen second
Explanation:
Answer:
C₃H₃NaO₂
Explanation:
The percentage composition of the artificial snow is given.
The smallest whole number ratio of the atoms in a compound gives the empirical formula.
To find the empirical formula of the artificial snow, we use the method below;
Percentage composition of oxygen = 100 - (38.3+3.33+ 24.4) = 33.97
Elements C H Na O
Percentage
Composition 38.3 3.22 24.4 33.97
Number of
moles 38.3/12 3.22/1 24.4/23 33.97/16
3.19 3.22 1.06 2.12
Divide by
the smallest 3.19/1.06 3.22/1.06 1.06/1.06 2.12/1.06
3 3 1 2
The empirical formula of the compound is C₃H₃NaO₂
