A chemical engineer must report the average volume of a certain pollutant produced by the plants under her supervision. Here are

the data she has been given by each plant:
Plant Volume of pollutant
Cross Creek 10.88 L
Oglala 0.92 L
Platte 15.82 L

What average volume should the chemical engineer report? Be sure your answer has the correct number of significant digits.

Answer:

9.2 L is the average volume should the chemical engineer report.

Explanation:

Volume of pollutant from Cross creek plants  10.88 L

Volume of pollutant from Oglala plants = 0.92 L

Volume of pollutant from Platte plants = 15.82 L

Average volume pollutants will be given by :

=\frac{10.88 L+0.92 L+15.82 L}{3}=9.2067 L\approx 9.2 L

9.2 L is the average volume should the chemical engineer report.

A balloon is filled with 35.0 L of helium in the morning when the temperature is 35.00 oC.
nexus9112 [7]

Answer: V = 33.9 L

Explanation: We will use Charles Law to solve for the new volume.

Charles Law is expressed in the following formula. Temperatures must be converted in Kelvin.

V1 / T1 = V2 / T2 then derive for V2

V2 = V1 T2 / T1

= 35 L ( 308 K ) / 318 K

= 33.9 L

If a penny (with the this volume .39 cm^3) was made out of pure copper, what should its mass be?
blondinia [14]

Answer:

  3.49 g

Explanation:

The mass is the product of volume and density:

  (8.96 g/cm³)(0.39 cm³) ≈ 3.49 g

The mass of a pure-copper penny would be 3.49 g.

How many moles in 3.69 x 10^30 molecules of carbon dioxide?
Sedaia [141]

0.612 \times 10^{7} \text { moles of } \mathrm{CO}_{2} are present in 3.69 \times 10^{30} \text { molecules of } \mathrm{CO}_{2}

<u>Explanation:</u>

It is known that each mole of an element is composed of avagadro's number of molecules. So if we need to determine, we need to divide the number of molecules with the avagadro's number.

So,

    1 mol of element =6.02 \times 10^{23} molecules of element

As here 3.69 \times 10^{30} molecules of carbon di oxide is given. So the moles in it will be

   No. of moles of carbon dioxide = \frac{3.69 \times 10^{30}}{6.02 \times 10^{23}}

    No. of moles = 0.612 \times 10^{7} moles of carbon dioxide.

Thus,

0.612 \times 10^{7} of carbon dioxide are present in 3.69 \times 10^{30} \text { molecules of } \mathrm{CO}_{2}.
