Answer:
d
Explanation:
I took this test way back
Density = mass/V = MW P / RT
density = 64.1 g/mol X 1.2 atm / 0.0821 Latm/molK (271K) = 3.46 g/L
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
A calorie is equal to 4.18 joules and 1000 calories is equal to 1 Calorie. A Calorie with a capital "c" is what food is measured in.
