Answer:
M

2.0
m

l
L
−
1
Explanation:
The molarity,
M
of this solution can be calculated by a formula which is;
M
=
n
V
where;
M
= Molarity of solution
n
=Number of moles of solute
V
= Volume of solution in Litre
Given,
n
=
4.0
moles and
V
=
2.0
L, so we have enough information to calculate the molarity of the solution;
M
=
n
V
M
=

because

Answer: In joints and bones
Explanation: Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs. Between the vertebrae in the spine. Your Welcome! :)
Adenine which is a purine base, always pairs with the pyrimidine Thymine in DNA and Uracil(also a pyrimidine) in RNA. The bond which is present between the two bases is a double hydrogen bond.
Guanine which is also a purine base, always pairs with the pyrimidine Cytosine, in the case of both, DNA and RNA. The bond which is present between the two bases is a triple hydrogen bond and hence, is stronger than the A-G double bond.
