Density = 1.0 g/mL
5.3 (w/w)% => 5.3 / 100 => 0.053
molar mass acetic acid = 60.05 g/mol
M = 1000. w . D / molar mass
M = 1000 . 0.053 . 1.0 / 60.05
M = 53 / 60.05
M = 0.882 mol/L
hope this helps!
Answer: density
Explanation:google
Answer : The ratio of the mass of a substance to its volume is called density. ... The unit of mass is gram (g) and the unit of volume is milliliter (ml). So, the unit of density is g/ml.
0.5 mg/mL would be expressed as 500 ug/uL
Hi!
The correct option would be A.
This is because the displacement reaction would take place as follows
Ca + ZnCl2 --> CaCl2 + Zn
A displacement reaction is one in which a substitution occurs, as the more reactive element in the mixture replaces one that is less reactive.
In the electrochemical series, we find Ca higher than Zn, which is indicative of Ca being more reactive, and having the capacity to displace Zn to form a compound.
Option D would be incorrect as no such substitution occurs.
Option B would be incorrect because again, there is no substitution occurring, and also because two metals alone (Ca and Zn in our case) can never react to form a compound.
Option C would be incorrect because it is not possible because CaCl and ZnCl are forms that are too unstable to exist due to an overall positive charge.
Hope this helps!
