Osmotic pressure can be calculated using the following equation:
Here,
C representated concentration
R represented gas constant
T represented temperature
representated osmotic pressure
R=0.0821 atm L mol ⁻¹
T = 25 + 273 = 298 K
C=
Given mass of the substance= 6.00 g
Volume= 1 L
=0.75 atm
Putting all the values in the equation:
Molar mass of the substance= 195 g mol⁻¹.
Answer:
the regulation of Soviet production of missiles that carried nuclear weapons
Explanation:
The aim of the SALT I agreement in 1972 was to stop or greatly reduce the arms race where world powers were stockpiling ballistic missiles and other nuclear arsenal.
Therefore, this agreement brought about the regulation of Soviet production of missiles that carried nuclear weapons
The substance which is a combination of different atoms is
compound
compound is substance formed when two ore more different atoms are chemically bonded together. example of compound H20 which is made up of which is made of two atoms of hydrogen and one atom of oxygen joined by a covalent bond to form water(H20)
I think it’s most likely a, but it could be D :)
The empirical formula of metal iodide : CoI₃(Cobalt(III) Iodide)
<h3>Further explanation</h3>
13.02 g sample of Cobalt , then mol Co(MW=58.933 g/mol) :
Mass of metal iodide formed : 97.12 g, so mass of Iodine :
Then mol iodine (MW=126.9045 g/mol) :
mol ratio of Cobalt and Iodine in the compound :
