Explanation:
Because molarity is classified as moles of solute per liter of water, dilution of the water may result in a reduction of its concentration.
Therefore, because the amount of moles of solute has to be constant for dilution, you will use the molarity and volume of that same target solution to calculate how many moles of solute will be present in the sample of the stock solution that you dilute.
c =
⇒ n
=
c
⋅ V
= 0.250 M ⋅ 6.00 L =
1.5 moles HCl
Now all you have to do is figure out what volume of 6.0 M stock solution will contain 1.5 moles of hydrochloric acid
c =
V =
= =
0.25 L
Expressed in milliliters, the answer will be
→ rounded to two sig figs
The answer is C
6.0m x 8.0m= 48.0m
then converting it to cm by multiply
48 x 100
<span>The number of atoms in 4.75 moles of gold (Au) is found using Avogadro's number, which is 6.022Ă—1023 mol-1. Determine the number of atoms by multiplying 4.75 moles by Avogadro's number. The number of atoms in 4.75 moles of gold is 2.8605172125000205e24.</span>
Answer:
Kinetic energy would have to work ten times harder than potential energy.
Explanation:
Let’s say you have a boulder and your asked to push it up the hill it would be difficult right? But lets reverse the situation what if you are asked to roll the boulder down the hill it wouldn’t be much work because the hill is basically doing all the work For you. Hope this Helps:)
