Answer:
0.104M
Explanation:
The following equation is given in this question:
mava=mbvb
Where;
ma = molarity of acid (M)
mb = molarity of base (M)
va = volume of acid (ml)
vb = volume of base (ml)
According to this inputted values;
max5.0ml=5.2mlx0.10m
ma = unknown molarity of acid
mb = 0.10M
va = 5.0ml
vb = 5.2ml
Hence, ma x 5.0ml = 5.2ml x 0.10m
5ma = 0.52
ma = 0.52 ÷ 5
ma = 0.104M
An afterglow may appear above the highest clouds in the hour of fading twilight or be reflected off high snowfields in mountain regions long after sunset. The particles produce a scattering effect upon the component parts of white light. The opposite of an afterglow is a foreglow, which occurs before sunrise.
