One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
(6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.
Ethanoic acid ionizes in aqueous solutions to form two ions which are
and 
<h3>Ionization of ethanoic acid</h3>
Ethanoic acid goes by the chemical formula
.
In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:

A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single

Answer:
See below.
Explanation:
pH = - log (H+)
So the pH of 1 x 10^-7 M solution is 7.
I'm sorry but I'm not sure about what the other units mean, so Im not sure of the answer to those.
If you convert the other units to the form 1 x 10^-n then the pH will be n.
<h2>
Answer: START (2)</h2>
Explanation:
AUG is a <u>START</u> codon. (2)
A start codon is the first codon translated by a ribosome. It usually produces an amino acid that initiates the producyion of a polypeptide chain.
