Answer:
subsystems.
Explanation:
A self-contained system within a larger system. system. A group of interacting or interdependent elements forming a complex whole, as in all the factors or variables in an environment or all the variables that might affect a science experiment.
Answer:
<h2>Density = 3.9 g/ mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 43 g
volume = 11.1 mL
Substitute the values into the above formula and solve for the density
That's
We have the final answer as
Density = 3.9 g/ mL to one decimal place
Hope this helps you
Copper wire is not an example of a pure element because although it's made by pure elements, it's not one itself. It's made by factories.
Have a nice day! :)
Ethanol is produced by the fermentation of the sugar of plants and it can be used as a fuel
in brasil they have a mass culture of using ethanol mixed with other hydrocarbons called biofuel

<span>Helium atom's Atomic Weight = He = 4.0026 g/mol.
Avagrado's number is = 6.023 x 10^23 molecules / mol.
In order to find the number of atoms in 535kg of helium blimp.
First we need to convert the weight of 535 kg to mol which can be done by multiplying the atomic weight of helium into present atom with respect to grams.
535 kg converted into grams ---> 535000 g
There fore 535000 g X 4.0026 g/mol = 133,663 mol. (Note The grams will get cancel as per multiplication rules)
Multiplying the avagadro's number with the equation we get:
133,663 mol *6.0221415 Ă— 10^23 molecules/mol= 8.04919303 Ă— 10^28 molecules.
Since Helium is having 2 Atoms :
8.04919303 Ă— 10^28 molecules *2= 1.60983861 Ă— 10^29 atoms
The No of Helium atoms in 535 kg of helium is 1.61 x 10^29.</span>
