400ml of 2.5M can be deluded to make how many of 2.0 HCI

The new volumen of the solution is 500 ml.

Explanation:

A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).

We use the formula for dilutions:

C1 x V1 = C2 x V2

V2= (C1xV1)/C2

V2= (400 ml x 2,5 M)/2,0M

V2= 500 ml

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
