Answer: 6.2 moles
Explanation:
C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g)
The balanced equation above shows the combustion of propane, C3H8 in oxygen, O2 to yield carbon dioxide, CO2 and water, H2O
The mole ratio of combustion are as follows:
1 mole of C3H8 react to produce 4 moles of H2O
1.55 mole of C3H8 will react to produce Z moles of H2O
To get the value of Z, cross multiply
Z x 1 mole = 1.55 mole x 4 mole
Z = 6.2 moles
Thus, 6.2 moles of water will be produced from 1.55 moles of propane
Answer:
0.54 L
Explanation:
Given that,
Initial volume, V₁ = 0.5 L
Initial temperature, T₁ = 10°C = 283 K
Final temperature, T₂ = 35 C = 308 K
We need to find the final volume. The relation between the volume and temperature is given by :
So, the new volume is 0.54 L.
Gold alloys consist of most commonly Nickel!
Most commonly used in things like jewelry so it doesn't have such a heavy weight.
