A molecule of an organic compound contains at least one atom of "<span>(1) carbon". This is referred to as organic chemistry, since all living matter is carbon-based. </span>
Answer:
, 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like
and
These units of temperature are inter convertible.
We are given:
Temperature of the gas =
Converting this unit of temperature into
by using conversion factor:
Converting this unit of temperature into
by using conversion factor:

Thus the temperature on the Celsius and Kelvin scales are
and
respectively.
Potassium (K) is in Group I of the periodic table, and elements in the same column (period) are similar. Sodium (Na), or lithium (Li) are similar.
<span>M(NO3)2 ==> [M2+] + 2 [NO3-]
0.202 M ==> 0.202 M
M(OH)2 ==> [M2+] + 2[OH-]
5.05*10^-18 ===> s + [2s]^2
5.05*10^-18 ===> 0.202 + [2s]^2
5.05*10^-18 = 0.202 * 4s^2
4s^2 = 25*10^-18
s^2 = 6.25*10^-18
s = 2.5*10^-9
So, the solubility is 2.5*10^-9</span>
