5L O2 x 1 mol O2/ 22.4L O2 x 2 mol H20/ 1 mol O2 x 22.4L H20/ 1 mol H20 = 10 L H2O
For future reference though, since its at STP that means that the coefficient are in proportion. Since oxygen has a coefficient of 1 and water has a coefficient of 2 for every 1 liter of oxygen there is 2 liters of water. Hence you started with 5 liters and ended with 10
<h3>
Answer:</h3>
Final volume is 120 L
<h3>
Explanation:</h3>
- Using the dilution concept, dilution involves adding more solvent to a concentrated solution to make it dilute. This results to a dilute solution with less solute concentration and more solvent.
According to the dilution equation;
M1V1 = M2V2
Where, M1 is the molarity and V1 is the volume of the concentrated solution, while M2 and V2 are the molarity and volume of the diluted solution respectively.
In this case;
M1 = 12.0 M
V1 = 30 L
M2 = 3.0 M
V2 = ?
Therefore;
V2 = M1V1 ÷ M2
= (12 × 30) ÷ 3
= 120 L
Hence, the final volume will be 120 liters
0.161 mols.
Balance the equation first
2Fe + O2 •••••> 2FeO
Find the molar masses of the compound
2(56) + 2(16) •••••> 2(56+16)
112g + 32g •••••> 144g
Fe reacting with O2
112g of Fe reacting with 32g of O2
18g of Fe reacting with x
x= 32×18/112
x= 5.143g
Amount= mass/ molar mass
Amount= 5.143g/32g
Amount= 0.161mls
If you mean as in like how to calculate the distance then it would be
speed x time
