Answer:
from,
moles,n = <u>number</u><u> </u><u>of</u><u> </u><u>particles</u><u>,</u><u> </u><u>N</u>
Avogadro constant
N = 8.27 * 6.022×10^23
N = 4.98 × 10^ 24particles.
In 8.27 moles of SiH, there are
4.98 × 10^24particles.
Hey there!
Atomic mass Bromine ( Br ) = 79.9 u
Therefore:
79.9 g Br --------------- 22.4 L ( at STP )
18.0 g Br --------------- volume ??
Volume Br = 18.0 * 22.4 / 79.9
Volume Br = 403.2 / 79.9
Volume Br = 5.046 L
hope this helps!
Answer:
The answer is
<h2>5.75 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 23 g
volume = 4 mL
The density of the object is
We have the final answer as
<h3>5.75 g/mL</h3>
Hope this helps you
Answer:
A
Explanation:
I would say a because we all know that kinetic energy is energy in motion and fuel is an example of chemical energy. So it must be from chemical to kinetic energy.
