Answer:
it's describes the velocity. since a direction was specifically given, that means it is displacement, and displacement is to velocity while distance is to speed
To get the formula mass we have to add the atomic mass of each atom
(55.847 x 2) + ( 16 x 3) = 160
this means that 16 x 3 = 48 are the grams of O
% = 48 x 100 / 160 =30 %
hope this helped mark me brainliest
The answer is c this is the answer
