Answer:
210 moles
Explanation:
From the question given above, the following data were obtained:
Volume of solution = 25.6 L
Molarity = 8.20 M
Mole of solute =?
Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:
Molarity = mole /Volume
With the above formula, the mole of solute dissolved can be obtained as follow:
Volume of solution = 25.6 L
Molarity = 8.20 M
Mole of solute =?
Molarity = mole /Volume
8.20 = mole / 25.6
Cross multiply
Mole = 8.20 × 25.6
Mole = 209.92 ≈ 210 moles
Thus, the mole of solute dissolved in the solution is 210 moles
Answer:
Name the non-metal furthest to the left on the periodic table by its elemental name.
Name the other non-metal by its elemental name and an -ide ending.
Use the prefixes mono-, di-, tri-.... to indicate the number of that element in the molecule.
im prolly wrong
Here we go, 4 attachments, you made me work LOL
The formula for speed is
s=distance/time
Substitute
s=1000m/250 sec
Divide
s=4 m/s
Hope this helps you
