The moon plays a huge factor in creating ocean waves
Moles= mass/Mr
Moles= 3.82/40
Moles= 0.0955 mol
Answer:
The concentration is 0.025 M.
Explanation:
We will use beer law to find the concentration.
A = εmCl
This law relate to the linear equation Y = mx + b in following way,
A = y = absorbance
m = εm = slope or extinction coefficient in beer law.
x = c = concentration
and l is length which is 1 cm
Thus equation can be written as,
A = εmc + b
A - b / εm = c
in order to find the concentration we will abstract the intercept from absorbance and then divide it by the slop.
0.02 - 0.011 / 0.36 = c
c =0.009
c = 0.025 M.
Answer:
gamma ray
Explanation:
Gamma emission results in the release of energy without any apparent change in mass or nuclear charge.
Properties of Gamma radiations:
Gamma radiations are high energy radiations having no mass.
These radiations are travel at the speed of light.
Gamma radiations can penetrate into the many materials.
These radiations are also used to treat the cancer.
Lead is used for the protection against gamma radiations because of its high molecular density.
The lead apron are used by the person when treated with gamma radiations.
Lead shields are also used in the wall, windows and doors of the room where gamma radiations are treated, in-order to protect the surroundings.
It depends on which manner the formulae is being asked but the answer is: KNO3
