Rate of reaction can be understood as the rate of change of the materials, such as the rate of depletion of the reactants or the rate of production of products. Therefore, if a graph of concentration and time is plotted, the rate of reaction is simply the slope of the graph.
Weight of Chloroform : = 2.862 kg
<h3>Further explanation</h3>
Given
Density 1.483 g/ml
Volume = 1.93 L
Required
Weight of Chloroform
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:

ρ = density
m = mass
v = volume
Convert density to kg/L :
=1.483g/ml = 1.483 kg/L
So the weight(mass) :
= ρ x V
= 1.483 kg/L x 1.93 L
= 2.862 kg
