Answer: The moles of gas present in the cylinder is 0.34 moles.
Explanation:
Given: 
= 2.7 atm, 
= 3.1 L, 
= 300 K
= ?, 
= 9.4 L, 
= 610 K
Formula used to calculate the final temperature is as follows.
Substitute the values into above formula as follows.
Now, moles present upon heating the cylinder are as follows.
Thus, we can conclude that moles of gas present in the cylinder is 0.34 moles.
Answer:
We write 50,000 in scientific notation,
it is written as 5 x 10⁴.
Hope it helps.
The elements in each group have the same number of electrons in the outer orbital<span>. Those </span>outer<span> electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its </span>outer<span> shell.</span>
Answer:
I <em>believe</em> it is Avogadro's number: 6.022 × 10²³
Explanation:
One mole of a substance is equal to 6.022 × 10²³ units of that substance
