An ecologist counts 75 cardinals in an area measuring 15 square kilometers. What is the population density of the cardinals?
Rom4ik [11]

<u>Answer:</u>

5

<u>Explanation:</u>

We know that,

number of count of cardinals = 75; and

measured area = 15 square kilometers.

To find the population density of the cardinals in an area of 15 square kilometers, we need to divide the number of cardinals by the given unit area:

Population density of cardinals = 75 / 15 = 5

Therefore, the population density of cardinals in an area measuring 15 square kilometers is 5.

If a metal rod has a density of 7.85 g/cm and a volume of 4 cm, then what is its mass?
Bond [772]

Answer:

<h3>The answer is 31.4 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of metal = 4 cm³

density = 7.85 g/cm³

The mass is

mass = 7.85 × 4

We have the final answer as

<h3>31.4 g</h3>

Hope this helps you

20 mL of an approximately 10% aqueous solution of ethylamine, CH3CH2NH2, is titrated with 0.3000 M aqueous HCl. Which indicator
Vinvika [58]

20 mL of an approximately 10% aqueous solution of ethylamine, CH3CH2NH2, is titrated with 0.3000 M aqueous HCl. Which indicator would be most suitable for this titration? The pKa of CH3CH2NH3+ is 10.75.

Answer:

Bromocresol green, color change from pH = 4.0 to  5.6

Explanation:

The equation for the reaction is as follows:

C_2H_5NH_{2(aq)     +     H^+_{(aq)      ⇄        C_2H_5NH_{3(aq)}^+

Given that concentration of C_2H_5NH_{2(aq) = 10%

i.e 10 g of C_2H_5NH_{2(aq) in 100 ml solution

molar mass = 45.08 g/mol

number of moles = \frac{10}{45.08}

= 0.222 mol

Molarity of C_2H_5NH_{2(aq) = 0.222 × \frac{1000}{100}mL

= 2.22 M

However, number of moles of C_2H_5NH_{2(aq) in 20 mL can be determined as:

number of moles of C_2H_5NH_{2(aq) = 20 mL × 2.22 M

= 44*10^{-3} mole

Concentration of C_2H_5NH_{2(aq) = \frac{44*10^{-3}*1000}{20}

= 2.22 M

Similarly, The pKa Value of C_2H_5NH_{2(aq)  is given as 10.75

pKb value will be: 14 - pKa

= 14 - 10.75

= 3.25

Finally, the pH value at equivalence point is:

pH= \frac{1}{2}pKa - \frac{1}{2}pKb-\frac{1}{2}log[C]

pH = \frac{14}{2}-\frac{3.25}{2}-\frac{1}{2}log [2.22]

pH = 5.21

∴

The indicator that is best fit for the given titration is Bromocresol Green Color change from pH between 4.0 to 5.6.
