The definition from what I know because I remember it from biology I think is "a theory explaining the structure of the earth's crust and some other associated phenomena as resulting from the interaction of a rigid lithospheric plates that move slowly over the underlying mantle." I'll put the quotations for you to copy what I said so it doesn't sound like you got it off me and I hopefully spelt lithospheric right
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
Explanation:
RAM={mass number ×relative abundance (%) + mass number ×relative abundance (%)} ÷100%
so take (91.05×20) +(8.95×22)
Answer:
Amount of salt needed is around 2.3*10³ g
Explanation:
The salt content in sea water = 3.5 %
This implies that there is 3.5 g salt in 100 g sea water
Density of seawater = 1.03 g/ml
Volume of seawater = volume of tank = 62.5 L = 62500 ml
Therefore, the amount of seawater required is:

The amount of salt needed for the calculated amount of seawater is:
