Answer:
In a balloon with a volume of 3.00 L gas, there is a total of 0.15 moles of gas.
If we add 0.15 moles to a balloon containing 0.10 moles, the new volume is 5 L
Explanation:
Step 1: Data given
Number of moles = 0.10 moles of gas
Volume of gas= 2.00 L
New volume = 3.00 L
Step 2: Calculate new number of moles
Avogadro's law says:
n1/V1 = n2/V2
⇒ with n1 = the number of moles of gas = 0.10 moles
⇒ with V1 = the volume of gas in the balloon = 2.00 L
⇒ with n2 = the number of moles when then volume changed to 3.00L
⇒ with V2 = the new volume = 3.00 L
0.10 mol / 2.00 L = n2 / 3.00 L
n2 = (0.10 * 3.00)/2.00
n2 = 0.15 moles
When adding 0.15 moles of gas to the balloon, the total number of moles is 0.25 moles, the total volume will be:
0.10 mol / 2.00 L = 0.25 moles / V2
V2 = 5 L
In a balloon with a volume of 3.00 L gas, there is a total of 0.15 moles of gas.
If we add 0.15 moles to a balloon containing 0.10 moles, the new volume is 5 L
