1 atm = 760 mm Hg
Where 760 mm is the height of Mercury for 1 atm.
For 0.900 atm,
Height of mercury = 0.900*760 = 684 mm Hg
<h3><u>Answer;</u></h3>
Atomic particles
The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.
<h3><u>Explanation</u>;</h3>
- Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
- <em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
- Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions
Answer:
no
Explanation:
Weight is a measure of how much gravity pulls on a mass or object. On the moon, there is less gravity pulling on objects, so they weigh less. ... But does its mass changejust because it is on the moon? No, it is still the same size and looks the same, it just has less gravity pulling on it, so it weighs less.
Answer:
C5H6N2O3
Explanation:
First the empirical formulas
C= 41.8÷12= 2.48
H= 4.7÷1= 4.7
O= 37.3÷ 16= 2.33
N= 16.3÷14 = 1.16
Divide by the smallest
C= 3.48/1.16=3
H= 4.7/1.16=4.1
O= 2.33/1.16=2
N= 1.16/1.16=1
Therefore empirical formula = C3H4NO2
To calculate molecular formula for osmotic pressure,
π= cRT
Or
π=cgRT/M where cg is in g/liter & T is temperature in Kelvin. Thus
π= (7.480*0.0821*300)/ M
M= 184.23/1.43
M= 128.83
To find molecular Formula
Molecular Mass= (empirical mass)n
128.83= (C3H4NO2)n
128.83= 86n
n= 1.5
Therefore the molecular formula
(C3H4NO2)1.5
= C4.5H6N1.5O3
Approximately
C5H6N2O3
