Answer:
<h2>Density = 0.75 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 450 g
volume = 6.0 × 10² mL
Substitute the values into the above formula and solve for the density
That's
We have the final answer as
<h3>Density = 0.75 g/mL</h3>
Hope this helps you
The charge on one mole of electrons = 96485 C = 1 Faraday
so if charge is 96485 C the moles of electrons are 1 = 6.023 X 10^23 electrons
if charge is 1 C the number of electrons = 6.023 X 10^23 / 96485
If charge is 50 micro C the number of electrons
= 6.023 X 10^23 X 50 X 10^-6 / 96485
= 3.12 X 10^14 electrons
Convection drives the earth's atmosphere and dictates the distribution of life in the world's oceans.
A question that can be tested scientifically are questions that can be answered through observations or through a well designed experiment that can provide evidence.
