What is the mass of 8.0 x 10^26 UF6 molecules?
gulaghasi [49]
First, find the number of moles of UF6
Avagadro's number = 6.023 x 10^23

Number of moles = 8.0 x 10^26 / Avagadro's number = 8.0 x 10^26 / 6.023 x 10^23 = 1.328 x 10³ moles

Molecular weight of UF6 = Molecular weight of U (238.02891) + Molecular weight of F6 (6 x 18.9984032) = 238.02891 + 113.9904192 = 352.0193292 g/mol

Therefore mass of 8.0 x 10^26 UF6 molecules = 352.0193292 g/mol x 1.328 x 10³ moles = 467.481669 x 10³ grams

How many molecules of ethanol (c2h5oh) (the alcohol in alcoholic beverages) are present in 155 ml of ethanol? the density of eth
ozzi

First convert volume to mass:

mass = 0.789 g/mL * 155 mL = 122.295 g

 

Then convert mass to number of moles:

number of moles = 122.295 g * (1 mole / 46 g) = 2.66 moles

 

Using avogadros number, we get the molecules:

<span>number of molecules = 2.66 moles * 6.022 x 10^23 molecules / mole = 1.6 x 10^24 molecules</span>

Review the map that shows earthquake zones as yellow lines and active volcanoes as red dots. what pattern can you determine abou
aleksandr82 [10.1K]

A map that shows the location of volcanoes is called a Geologic Map. This kind of map contains information about the geological history and condition of volcanic sites.

<h3>What do Geologic Maps indicate?</h3>

Geologic maps indicate the following:

  • the location of volcanos
  • age of rock deposits found near the volcano
  • which volcanoes are active and those that aren't
  • types of rocks at these sites
  • faults fracture etc.

Note that the map specific to the question is unavailable hence the general response.

Kedrick and Kaleb train by pushing a sled that weighs 300 kg at an acceleration of 2m/s^2. What force did they push the sled wit
stiks02 [169]

Answer:

\boxed {\tt 600 \ Newtons}

Explanation:

Force can be found by multiplying the mass and the acceleration.

F=m*a

The mass of the sled is 300 kilograms and the acceleration is 2 meters per second squared.

F= 300 \ kg * 2 \ m/s^2

Multiply.

F= 600 \ kg * m/s^2

1 kilogram-meter per second squared is equal to 1 Newton. Therefore, 600 kilograms-meter per second squared is equal to 600 Newtons.

F= 600 \ N

The force used on the sled is 600 Newtons.
