I think it’s B) Molecules
I searched it up
The molarity of KCl solution made by diluting 75.0 ml of a 0.200M solution to a final volume of 100ml is calculated using the below formula
M1V1=M2V2
M1=0.200 M
V1= 75.0 Ml
V2= 100 ml
M2=?
by making M2 the formula of the subject M2 =M1V1/V2
=75.0 ml x0.200 M/100 Ml = 0.15 M
Answer:
the answer is true
Explanation:
as sound travels through the air it creates a disturbance in the particles of the medium
1 mole -------- 22,4 L ( at STP )
0.030 moles --- ?
V = 0.030 * 22,4 / 1
V = 0.672 L
hope this helps!
