Answer:
0.025 g C6H12O6
Explanation:
ppm = (g solute/ g solution)* 10^6
g solute= (ppm * g solution)/ 10^6
g solute = (250 ppm * 100 g)/10^6
g solute=0.025 g C6H12O6
Answer:
Bohr model A
Explanation:
It has more valance electrons therefore has more interaction between the atoms and has more electronegativity.
Taking into account the definition of molarity, the molarity of a solution prepared by dissolving 0.2 mol sucrose in enough water to make a 100 mL solution is 2
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
![molarity=\frac{number of moles}{volume}](https://tex.z-dn.net/?f=molarity%3D%5Cfrac%7Bnumber%20of%20moles%7D%7Bvolume%7D)
Molarity is expressed in units
.
<h3>Molarity in this case</h3>
In this case, you have:
- number of moles= 0.2 moles
- volume= 100 mL= 0.1 L
Replacing in the definition of molarity:
![molarity=\frac{0.2 mole}{0.1 L}](https://tex.z-dn.net/?f=molarity%3D%5Cfrac%7B0.2%20mole%7D%7B0.1%20L%7D)
Solving:
<u><em>molarity= 2 </em></u>![\frac{moles}{liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%7D%7Bliter%7D)
Finally, the molarity of a solution prepared by dissolving 0.2 mol sucrose in enough water to make a 100 mL solution is 2

I don’t really know but I’ll get someone to help u
Hey there!:
H is always +1 so the H's have a +3 charge.
O is always -2 so the O's have a -8 charge .
Now, suppose oxidation state for P = X , then :
+3 + X + (-8) = 0 (because of neutral molecule)
x = 8 - 3
x = + 5
So, X = +5 oxidation state.
Answer C
Hope that helps!
