0.2 is the correct answer and shown above is the shown work
Answer:
Molarity of dextrose = 0.03 mol / L
Explanation:
Given data
mass of dextrose = 5 g
Concentration (Molarity) = ?
Solution
as mass is given so we find out number of moles
<em>Moles = mass / molar mass</em>
Molar mass of dextrose = 180.156 g/mol
Moles = 5 g / 180.156 g/mol
Moles = 0.03 moles
Now we find out molarity
<em>Molarity = moles of solute / Litres of solution</em>
As volume is not given so we suppose it as 1 L
Molarity of dextrose = 0.03 mol / 1 L
Molarity of dextrose = 0.03 mol / L
Answer:
ions have are charged and molecules are not
Explanation:
Here is an image of the periodic table. Hope this helps.
0.25 g al should equal around 0.009265594867125 moles
I hope this help
