Answer:
I believe it is "Arsenenate"
It is 0.5474 but you can put 0.5 hope this helps
Answer:
the third one because oceans don't affect the weather
Explanation:
Volume = Mass / Density
Volume = .842 / 2.70
Volume = .31185 cubic centimeters
Aluminum square * depth = .31185 cubic centimeters
6 * 6 * depth = .31185 cubic centimeters
depth = (.31185 cubic centimeters) / 36

centimeters
(That must be aluminum foil.)

Atomic mass of Potassium = Mass of 1 atom of Potassium = 39.1 amu
Then
Mass of 6.02 x 1023 atoms of potassium = 39.1 x 6.02 x 1023 amu
=
We already know that
1 mole = 6.02 x 1023 atoms
Also
Number of mole = mass in grams/ atomic mass
Then
Mass in gram = Number of mole x atomic mass
= (39.1 x 6.02 x 1023)/(6.02 x 1023)
= 39.1 g
The correct option among all the options that are given in the question is the third option or option "B".
