If we are comparing two different things to each other on Earth, they are pulled the same by gravity and so the one with more mass weighs more. But in space, where the pull of gravity is very small, something can have almost no weight. It still has matter in it, though, so it still has mass.
The mass percent of sugar in the solution is 1.225%
<u><em>calculation</em></u>
mass percent = [(mass of solute /mass of solution ) x 100]
mass of solute ( mass of a substance that dissolve in another substance)
= 2.45 g
mass of solution( mass of a substance that dissolves a solute) =200.0 g
Therefore mass percent = 2.45 g/200.0 g x 100 = 1.225% of sugar in solution
Answer:
<em>The first three options given out of the five options are correct.</em>
- <em>It collects chemical data.
</em>
- <em>It records real-time sampling data.
</em>
- <em>It processes and stores chemical data.</em>
Explanation:
An electronic air sampler is a device that is used by people to check apprehension of contamination having individuals with the help of certain volume of air sampling.
The Device is used for recording the chemical data of contamination and the real-time data is sampled and recorded and the data is processed and stored. The air sampling is done in two ways.
Answer:
Water can be used as the thermometric liquid. It expands and contracts with temperature so it can be used. It's just not a very good choice because: It's thermal expansion is not very large compared to other liquids like mercury.
Explanation:
Hope this help
