Answer:
We need 8.7 mL of the stock solution
Explanation:
Step 1: Data given
Volume of the solution he wants to prepare = 50.0 mL = 0.050 L
Concentration of the solution he wants to prepare = 0.80 M
The concentration of the stock solution = 4.6 M
Step 2: Calculate the volume of the stock solution
C1*V1 = C2*V2
⇒with C1 = the concentration of the stock solution = 4.6 M
⇒with V1 = the volume of the stock solution = TO BE DETERMINED
⇒with C2 = the concentration of the prepared solution = 0.80 M
⇒with V2 = the volume of the prepared solution = 0.050 L
4.6 M * V2 = 0.80 M * 0.050 L
V2 = (0.80 M * 0.050 L) / 4.6M
V2 = 0.0087 L = 8.7 mL
We need 8.7 mL of the stock solution
Answer:
The answer is : Yes
Explanation:
because it 12:00 and the storm is moving at 25km/hr and it 75 km away that means in three hours the storm would hit your town so at 3:00 the storm would hit at your at ends at 2:00 so yes you would get home before he storm hit.
Answer:
a element
Explanation:
In science copper is a element. It is one of the transition metals found on the periodic table of elements.
Elements are distinct substances that cannot be split-up into simpler substances. Such substances consist of one kind of atom.
There are over a hundred elements that are known till date.
Each elements combines to form a compound
The answer would be B: In the Earth’s atmosphere!.
