Answer:
The original concentration of ethanol is 16%(v/v)
Explanation:
concentration before dilution, C1 = ?
Concentration after dilution, C2 = 0.32% (v/v)
Volume before dilution, V1 = x
Volume after dilution, V2 = 50x
From the dilution principle
C1V1 = C2V2
(C1) * x = (0.32) * 50x
C1 = (16x)/x
C1 = 16%(v/v)
Answer:(1)=current (2)=force (3)=magnetic field (4)=reverse
Explanation:When there's a current in The coil. A force act on each side Of The coil. This is because the coil is in a magnetic field, the direction Of The spin would reverse
Electric circuit. Hoped that helped
