Answer:
The right answer is V = 17.2 mL
Explanation:
- Knowing that the the relation between No. of moles and concentration:
No. of moles = C * V
where,
C is the concentration in morality and
V is the volume in liter
so you can calculate the volume using:
V = (No. of moles / C) = (0.0131 mol / 0.763 mol/L)
V = 0.0172 L
- Then yo need to convert the volume from Liter to milliliter
V = 0.0172 L * (1000 mL / 1 L)
V = 17.2 mL
So, the right answer is V = 17.2 mL
Answer:
CH4 + 2 O2 → CO2 + 2 H2O
Explanation:
There are one mole of O2 on the left side and on the right side there are three moles of O2. And to fix it you would need to make it two moles of O2 to have four molecules of O2 on the left side. Then you would make two moles of H2O to have a total of four moles of O2 on the right. Therefore, CH4 + 2 O2 → CO2 + 2 H2O is the answer.
It's a dilute solution! So the answer would be C.
