Which has more particles? 10.0 g of Carbon or 10.0 g Calcium? How many atoms does each have?
1 answer:
Answer:
10g Carbon has more particles.
Explanation:
To Find
Which has more particles 10g of C or 10g of Ca
The molar mass of carbon is 12g and Calcium is 40g.
1 mole of atom , molecule or ions contain Avagadro number (6.022×10∧23) of particles and also have a mass equal to it's molar mass.
For C,
12g C will have 6.022×10∧23 atoms
10g C will have ×6.022×10∧23 atoms
=0.833 × 10∧23 atoms
For Ca,
1 mole Ca =40g
40g Ca will have 6.022×10∧23 atoms
10g Ca will have ×6.022×10∧23 atoms
=0.25 × 6.022×10∧23 atoms

Explanation:
The given data is as follows.
= 1.50 L,
= 159 K,
= 5.00 atm,
= 0.2 L,
= ?,
= 50.0 atm
And, according to ideal gas equation,
Hence, putting the given values into the above formula to calculate the value of final temperature as follows.
= 21.27 K
Thus, we can conclude that the final temperature is 21.27 K .
