The correct answer is 0.9803 atm
Given, pressure of nitrogen = 745 mmHg
Conversion factor: 760 mmHg = 1 atm
Converting 745 mmHg to 1 atm
745 mmHg x ( 1 atm / 760 mmHg) = 0.9803 atm
So is the pressure of nitrogen is 0.9803 atm
Answer:
126 g of H₂O
Explanation:
Firstly, we complete the equation:
2H₂ + O₂ → 2H₂O
If we have 7 moles of hydrogen, we assume, the oxygen is in excess.
Ratio is 2:2.
2 moles of hydrogen can produce 2 moles of water
Then, 7 moles of H₂ must produce 7 moles of water.
We convert moles to mass → 7 mol . 18 g/mol = 126 g
“Flow is the volume of fluid that passes in a unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), or other various units.”
The number of atoms that are present in 24g Carbon sample is
<h3>What is atom?</h3>
An atom can be regarded as the basic building block of chemistry and it is the smallest unit.
The Relative Molecular Mass of Carbon is known to be (12 g)
The Mass of the item was given as 24 g
Then we can find the Moles as ( 24g Carbon sample/24 g) = 2
Then the Number of atoms can be calculated as the
( Avogadro Number*Moles)
Therefore, the number of atoms that are present in 24g Carbon sample is 12.044*10^23
