Answer:
0.00663 grams/liter
Explanation:
HCl is a mineral acid with a molar mass of 36.46 g/mol.
No. of moles= mass/RMM
Making mass the subject of the formula:
Mass=Number of moles × RMM
Therefore 0.00040 mol HCl has a mass of:
0.00040 mol × 36.46 g/ mol
=0.01458 grams.
0.01458 grams are in 2.2 liters, Therefore 1 liter will have
0.01458 grams/2.2 liters= 0.00663 grams
concentration= 0.00663 grams/liter
Answer:
The total pressure of the mixture is 5, 53 atm.
Explanation:
The sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of said mixture, according to Dalton's law. We convert the unit of pressure in mmHg into atm:
760 mmHg----1 atm
785 mmHg----x= (785 mmHgx 1 atm)/760 mmHg=1, 03 atm
P total= P 02 + P N2
P total= 4, 5 atm + 1,03 atm=5, 53 atm
Answer:
In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.
