Answer: 1.037M
Explanation:
Since the rate constant unit is per seconds, therefore it is a first order reaction.
First order reaction equation is given as
InA= -kt +InAo
Where,Ao is the initial concentration of reactant =0.600M
A is the concentration of reactant at a specifies time t=3×60=180s
and k is the rate constant
InA = -6.50×10^-3 ×180 +In(0.6)
InA = -1.17 + 0.5108
InA= -1.680
A = e-1.680
A= 1.037M
Therefore the concentration after 3minutes is 1.037M
True, forces do change the motion of an object
1 mole CO₂----------- 6.02x10²³ molecules
4 moles CO₂ ---------- ??
4 x ( 6.02x10²³) / 1 =
= 2.41 x 10²⁴ / 1 => 2.41 x 10²⁴ molecules of CO₂
