N (H2O) = m/M
m (H2O) = 1.4 kg = 1400g
M (H2O) = 2 x 1 + 16 = 18g/mol
n (H2O) = 1400/18 = 77.8mol
Answer:
the process by which plants make their food by there own with the help of sunlight and water is known as photosynthesis
The mass of this much chain is 0.22 grams for 7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car.
<h3>What are weight and mass?</h3>
Mass is the amount of the substance and object and the weight is the gravitational force required to act upon the particular mass of the substance.
To calculate the mass of car divide the wight to the gravity value 9.8 meter per second.
mass = weight / gravity
substituting the value,
mass = 2.16 / 9.8
mass = 0.22 grams
Therefore,7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car the mass will be 0.22 grams.

Answer:
The phosphodiester connects the 3′ carbon of one nucleotide to the 5′ carbon of another nucleotide
Explanation:
The phosphodiester bond is a covalent bond where a phosphate group is attached to adjacent C through an ester bond, which is a consequence of a condensation reaction between the two sugar hydroxyl groups and the phosphate group.
The diester bond between phosphoric acid and two sugar molecules in the DNA and RNA skeleton binds two nucleotides forming polymers known as oligonucleotides.
The phosphodiester bond binds a C3` with a C5` in both DNA and RNA
(base)1-(sugar)-OH + HO-P(O)2-O-(sugar)-(base)2
------>
------> (base)1-(sugar)-O-P(O)2-O-(sugar)-(base)2
During the reaction of two of the hydroxyl groups in phosphoric acid with a hydroxyl group in two other molecules two ester bonds in a phosphodiester group are formed. A condensation reaction in which a water molecule is lost generates each ester bond.
