Answer:
initial temperature=
Explanation:
Assuming that the given follows the ideal gas nature;
mole of gass will remain same at any emperature:
putting all the value we get:
initial temperature=
Salt and Water is the correct answer.
hope this helps!
If a hypothesis is stated and outcome of the experiment is what was predicted, then it supports the hypothesis. if the experiment does not support the hypothesis, then the outcome was not what was predicted.
In science, we have a name for this, called Avogadro's number, and it describes the number of representative particles in one mole of a substance. The inverse mole unit tells us there are 6.022×1023 particles of something *per mole* so there are 1,023 particles
Answer:
The answer is
<h2>0.34 cm³</h2>
Explanation:
The denisty of a substance can be found by using the formula
<h3>
</h3>
Making volume the subject we have
<h3>
</h3>
From the question
mass = 4.62 g
Density = 13.5 g/cm³
Substitute the values into the above formula and solve for the volume
That's
<h3>
</h3>
= 0.34222……
We have the final answer as
<h3>0.34 cm³</h3>
Hope this helps you
