Answer:
19.79%
Explanation:
mass % = (mass solute / total mass) * 100
total mass = 129.54 + 525 = 654.54
solute = C6H12O6
(129.54/654.54) = .1979
.1979 * 100 = 19.79%
The percent of O in Cr₂O₃ : 31.58%
<h3>Further explanation</h3>
Given
Cr = 52.00 amu, O = 16.00 amu
Required
The percent of O
Solution
MW Cr₂O₃ = 2 x Ar Cr + 3 x Ar O
MW Cr₂O₃ = 2.52+3.16
MW Cr₂O₃ =152 amu
I believe the answer would be a.
My main reason would be momentum – it depends on the mass as
well as the speed of the colliding objects. For example if two sedans
travelling in a low speed bump each other, then probably the damage would be
minimal scratches. However, if a high speed car crashes unto a heavy truck also
travelling fast, then the result would be catastrophic.
