Collect the molar masses of each element contained in LiOH.

Lithium (Li) has a molar mass of 6.941 g/mol
Oxygen (O) has a mass of 15.999 g/mol
Hydrogen (H) has a mass of 1.008 g/mol

Together, LiOH has a molar mass of 23.948 g/mol.

Convert the given amount of LiOH from g to mol:

(67.03 g) * (1/23.948 mol/g) = 2.799 mol

What is the concentration after 11 minutes? Ground to 3 decimal places.

sergiy2304 [10]

In order to find the concentration after 11 minutes, let's use the value of t = 11 in the function C(t) and then calculate its value:

$\begin{gathered} C(t)=0.04(1-e^{-0.2t}) \\ C(11)=0.04(1-e^{-2.2}_{}) \\ C(11)=0.04(1-0.1108) \\ C(11)=0.04\cdot0.8892 \\ C(11)=0.035568 \end{gathered}$

Rounding to three decimal places, we have a concentration of 0.036.

wariber [46]

Answer:

a)e^-(λ20891)

b)1-e^-(λ30598)

c)1-e^-(λ30598)-e^-(λ20891)

Step-by-step explanation:

The probability density function (pdf) of an exponential distribution is

f(x,λ)=λe^-(λx) for x>0, and 0 for x<0

The cumulative distribution function is given by

F(x,λ)=1-e^-(λx) for x>0, and 0 for x<0

P(X≥20891)=1-P(X≤20891)=1-F(20891,λ)=e^-(λ20891)

P(X≤30598)=F(30598,λ)=1-e^-(λ30598)

P(20891≤X≤30598)=F(30598,λ)-(20891,λ)=1-e^-(λ30598)-e^-(λ20891)
