Explanation:
mass = desity × volume
volume = mass/density...
i believe thats right...
btw u means Physics formulae only..lol
Answer:
- <u>Second choice: </u><em><u>How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns?</u></em>
<u></u>
Explanation:
Science or scientific investigations deal with objective phenomena; this is phenomena which can be described by using objective measurements.
The effect of the position of the Sun, moons, planets and stars on a person's personality and daily behavior patterns is not a scientific question because none scientific field deals with that kind of questions.
Only, a pseudoscience, this is a set of beliefs that have not been scientifically proved, may deal with a question about the effect of the position of some heavenly objects can affect a person's personality traits and daily behavior of patterns.
On the other hand, the aspects deal with in the other questions (the mass of a toy car, the speed down a ramp, the heating from different type of pans, how different type of chemicals remove the cell wall of a plant cell) are measurable and testable (falsifiable), which make them objects of science (like physics, chemistry, and biology)
You would go into negative numbers and keep subtracting.
For example, 3-4 is -1 and 4-7 is -3.
Hope you know how to do it!!!
Answer : The molality of solution is, 0.866 mole/kg
Explanation :
The relation between the molarity, molality and the density of the solution is,
![d=M[\frac{1}{m}+\frac{M_b}{1000}]](https://tex.z-dn.net/?f=d%3DM%5B%5Cfrac%7B1%7D%7Bm%7D%2B%5Cfrac%7BM_b%7D%7B1000%7D%5D)
where,
d = density of solution = 1.0052 g/ml
m = molality of solution = ?
M = molarity of solution = 0.828 M = 0.828 mol/L
= molar mass of solute (acetic acid) = 60.05 g/mole
Now put all the given values in the above formula, we get the molality of the solution.
![1.0052g/ml=0.828mol/L\times [\frac{1}{m}+\frac{60.05g/mole}{1000}]](https://tex.z-dn.net/?f=1.0052g%2Fml%3D0.828mol%2FL%5Ctimes%20%5B%5Cfrac%7B1%7D%7Bm%7D%2B%5Cfrac%7B60.05g%2Fmole%7D%7B1000%7D%5D)
Therefore, the molality of solution is, 0.866 mole/kg
