<span>hexa stands for 6, so this molecule has 1 sulfur atom, surrounded by 6 fluorine atoms.</span>
Answer:
The given statement is false.
Explanation:
A solution is made up two components that is solute and solvent.
Solution = Solute + Solvent
Solute is defined as a component present in a solution in lessor amount.
Solvent is defined as a component present in a solution in greater amount.
In the given sugar solution, glass of water with sugar is dissolved which clearly depicts that sugar is solute and water is solvent.
Answer:
0.0329g of quinine
Explanation:
If 25.0ppm of quinine solution had a fluorescence of 193, the solution that had a fluorescence of 127 has as concentration:
127 × (25.0ppm / 193) = <em>16.45ppm</em>
<em />
As the solution was diluted from 50.0mL to 200.0mL, the sample tonic of water contains:
16.45ppm × (200.0mL / 50.0mL) = 65.8 ppm
As the original solution contains 500.0mL, mass of quinine is:
0.5000L × (65.8mg / L) = 32.9mg ≡<em> 0.0329g of quinine</em>
