As the question tells you, you need to use the formula
% mass= mass of solute/ mass of solution x 100
mass solute= 30.0 g
mass of solution= 30.0 + 270.0= 300.0 g
% mass= 30.0/ 300.0 x 100= 10%
answer is B
The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
EM is created by moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light
