Answer:- 1.62 moles
Solution:- At constant temperature and pressure, volume is directly proportional to the moles of the gas.
![\frac{V_1}{V_2}=\frac{n_1}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%3D%5Cfrac%7Bn_1%7D%7Bn_2%7D)
from given data,
= 5.17 L,
= 1.05 moles
= 8.00 L,
= ?
Let's plug in the values in the formula:
![\frac{5.17L}{8.00L}=\frac{1.05moles}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7B5.17L%7D%7B8.00L%7D%3D%5Cfrac%7B1.05moles%7D%7Bn_2%7D)
On cross multiply:
![n_2=\frac{8.00L(1.05moles)}{5.17L}](https://tex.z-dn.net/?f=n_2%3D%5Cfrac%7B8.00L%281.05moles%29%7D%7B5.17L%7D)
= 1.62 moles
So, now the toy contains 1.62 moles of the air.
Answer:
ACTIVITY 1
Sample 1 has a stronger taste of lemon, and is more sour.
Sample 2 has a sweeter taste, my guess is because there's more sugar:lemon juice ratio.
1.3 x 10^21 atoms Na is 4.63230769231 mol Na
4.63230769231 mol Na * 23g/mol Na = 106.543076923g
