Answer : The volume of solution will be, 0.309 L
Explanation : Given,
Mass of = 449.4 g
Molar mass of = 132 g/mole
Concentration = 11 M
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the volume of solution will be, 0.309 L
Answer:
Chromatography is used to separate mixtures of substances into their components.They all have a stationary phase (a solid, or a liquid supported on a solid)
Explanation:
it's where the things stay still until the mobile phase moves through and takes the components
Answer:
Explanation:
1. Atomic mass of K
To get the atomic mass of K, you calculate the weighted average of the isotopic masses.
That is, you multiply the atomic mass of each isotope by a number representing its relative importance (e.g., its percent of the total).
Set up a table for easy calculation:
2. Formula mass of KF
It means there is a lot of the same thing and not many others
Answer:
<h3>The answer is 7.14 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = final volume of water - initial volume of water
volume = 52.1 - 50.7 = 1.4 mL
We have
We have the final answer as
<h3>7.14 g/mL</h3>
Hope this helps you
