Density is defined as the ratio of mass to the volume.
Density =
(1)
Mass of water = 10 grams
Mass of acetone = 10 grams
Density of water = 1 
Density of acetone = 0.7857 
Put the value of density of water and its mass in equation (1)
1
= 
Volume of water = 10 
Put the value of density of acetone and its mass in equation (1)
0.7857
= 
Volume of acetone = 12.72 
Thus, volume of acetone is more than volume of water because the density of acetone is lower.
3.125 i believe is the answer
Answer:
Lmol⁻¹s⁻¹
Explanation:
The rate law of the given reaction is:-
Rate=k[A][B]
Wherem, k is the rate constant.
Given that:-
Rate = 0.36 mol/Lsec = 0.36 M/sec
[A] = 3.0 M
[B] = 1.0 M
Thus,
Applying in the equation as:-
0.36 M/sec =k × 3.0 M× 1.0 M
k = 0.12 (Ms)⁻¹ = 0.12 Lmol⁻¹s⁻¹
<u>The units of k = Lmol⁻¹s⁻¹</u>
