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
.
double displacement
bcoz each of the reactants combines with other reactants to obtain the product
Avegadro's number = 6.02 x10^23 atoms
so
3.5g x 1mol/63.55g Cu x 6.02 x 10^23/ 1mol=3.32 x 10^22 atoms
