Answer: There are formula units
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mole of contains = formula units
Thus 0.38 moles of contains = formula units
Thus there are formula units
Answer:
The answer to your question is 0.54M
Explanation:
Data
Final concentration = ?
Concentration 1 = 0.850 M
Volume 1 = 249 ml = 0.249 l
Concentration 2 = 0.420 M
Volume 2 = 0.667 M
Process
1.- Calculate the number of moles in both solutions
Number of moles 1 = Molarity 1 x Volume 1
= 0.850 x 0.249
= 0.212
Number of moles 2 = Molarity 2 x Volume 2
= 0.420 x 0.667
= 0.280
Total number of moles = 0.212 + 0.280
= 0.492
2.-Calculate the final volume
Final volume = Volume 1 + Volume 2
Final volume = 0.249 + 0.667
= 0.916 l
3.- Calculate Molarity
Molarity = 0.492 / 0.916
Molarity = 0.54
When collecting gas over water, the gas is always a mixture of the gas collected and water vapor. This statement is true.
The gaseous phase of water is known as water vapor or aqueous vapor. Within the hydrosphere, it is one type of water state. Water vapor can be created by the boiling or evaporation of liquid water as well as by the sublimation of ice. Like the majority of other atmospheric elements, water vapor is transparent. The mist that hovers above a saucepan of boiling water is an illustration of water vapor.
Gaseous water, particularly when it is distributed in the atmosphere. Steam. The most frequent greenhouse gas is water vapor. It contributes to around half of the planet's warming. It absorbs heat that is projected upward from the earth while letting practically all sunlight reach the planet's surface like other greenhouse gases do.
