For the 1st order reactions,rate constant (k) is mathematically expressed as
k =

where, t = time
Co = initial conc. of reactant
Ct = conc. of reactant after time 't'
Given: k = <span>2.20 × 10^-5 s-1, t = 2 hours = 7200 s
Therefore, we have
</span>2.20 × 10^-5 =

∴

= 0.06877
∴,

= 1.1716
∴, Ct = 85.35%
Thus, <span>
85.35 % of the initial amount of SO2Cl2 will remain after 2.00 hours.</span>
<span>There are a number of ways
to express concentration of a solution. This includes molarity. It is
expressed as the number of moles of solute per volume of the solution. To convert the mass of the solute to moles, we use the molar mass of the substance. We calculate as follows:
MOlarity = 4.725 g ( 1 mol / 58.45 g ) / .5 L = 0.162 mol / L</span>
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
The height of the bin is 29.9m.
The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
The total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.
The radius of the cylinder, r = 5m
Surface area = 1099 m²
∴ A = 2πrh + 2πr²





Therefore, the height of the bin is 29.9m.
