1718 l of a 0.3556-m c3h7oh solution is diluted to a concentration of 0.1222 m, what is the volume of the resulting solution

Answer : The volume of the resulting solution will be 0.4999 L.

Explanation : As the two molar concentration of the  solution are given and one of the volume concentration needs to be found.

So, according to the formula :-  

And here if we consider  as 0.1718 L moles and   as 0.3556 moles then we need to find  as   is given as 0.1222 moles.
Hence on solving the formula we get,  

  = (0.1718 X 0.3556) / 0.1222 = 0.4999 L

 

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
