Answer:
How are density, mass and volume related to each other? How do ... This diagram compares the particles in a gas, a liquid and a solid. ... The following diagram represents one of the glasses pictured above, containing a colourless liquid ... For matter to change from one state to another, its particles must gain or lose energy.
Explanation:
The volume of the new solution is calculated using the formula below
M1V1 = M2V2
M1= 15.0 M
V1= 50.0 ml
M2=2.50 M
V2=?
V2=M1V1/V2
=50 ml x 15m/2.5 M =300 ML
