Sqrt(mass2/mass1)
>>sqrt(14/2)
(Note:Hydrogen must exist in dwiatomic, [H2])
Buoyancy is considered a physical property. It is a type of physical property because it is related to the density and weight of the item, which are both physical.
They are called meteorologists. i hope this helped.
If you consider the motion of the slinky as just one object, you can look at it's center of mass. From the whole slinky point of view, there is only one force on the slinky - the gravitational force. This means that it falls and accelerates downward with an acceleration of -9.8 m/s2 just like all free-falling objects. Plze mark brainiest
Answer:
THE INITIAL VOLUME OF THE STOCK SOLUTION IS 0.0392 L OR 39.2 mL
Explanation:
To calculate the volume of a solution before dilution, we make use of the dilution formula;
C1 V1 = C2 V2
C1 = the concentration of the stock solution = 15 M
V 1 = the volume of stock solution = ?
C2 = concentartion of final solution = 2.35 M
V2 = volume of final solution = 250 mL = 250/ 1000 = 0.25 L
Rearranging the formula, we obtain;
V1 = C2V2 / C1
V 1 = 2.35 * 0.25 / 15
V1 = 0.5875 / 15
V1 = 0.0392 L
the initial volume of the stock solution is 0.0392 L or 39.2 mL
