As we know that
<span>V1/T1 = V2/T2
V1 = 9.10 L
T1 = 471 K
V2 = 2.50 L
T2 = 2.5 x 471 / 9.10 = 129.3 K
T2 = 129.3 - 273 =

Answer:
5 litres of solution are requried
Explanation:
Given that the typical units of
concentration
are
m
o
l
⋅
L
−
1
, to get
concentration
or
amount of moles
or
volume of solution
we just have to take the appropriate product or quotient.
We want
1.0
⋅
m
o
l
N
a
O
H
:
this the product
Volume of solution
×
Concentration
.
So we need the quotient:
Moles of solute
Concentration
=
1.0
⋅
m
o
l
0.2
⋅
m
o
l
⋅
L
−
1
=
5
⋅
L
.
(i.e.
1
1
⋅
L
−
1
=
1
⋅
L
)
Note that we go to such trouble in including the units in these calculations as an extra check on our arithmetic. Sometimes you ask yourself should I divide or should I multiply. Dimensional analysis answers our question. We wanted an answer in
litres
, and we got one. This persuades us that we did the calculation right.

Answer:
size-humans brains are usually larger than animals, shape-some animal brains are shaped very odd, and the cerebrum-that is the part of the brain that makes us human.
