Hey there!
V/V % = ( volume of solute ( mL ) / volume solution ) * 100
volume solute = 25 mL acetone
Volume solvent = 75 mL water
So :
v/v = 25
------------ * 100
25 + 75
v/v = ( 25 / 100 ) * 100
v/ v = 25%
hope this helps!
it causes bacteria and viruses from human and animal waste, and a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, and typhoid.
Assuming that the force of friction does not equal to the force at which you are pulling at, hence Fnet is not zero, to solve for acceleration need to use the following equation:
Fnet = ma
a = Fnet/m
a = 50 N/10 kg
a = 5 N/kg or a = 5 m/s^2.
