Answer: 6.25 mol
Explanation:
From the reaction that produces water from its elements (shown in the image), we know that for every mole of oxygen gas consumed, 2 moles of water are produced.
This means that 12.5/2=<u>6.25 mol</u> of oxygen gas is needed.
Ionic compounds conduct electricity when dissolved in water, because the free-floating ions can carry charge. The more ions you have, the more readily the solution will carry that charge. 10.0 mL of 0.10 M NH4Cl has only 0.001 mol of NH4+ and 0.001 mol of Cl-, whereas 10.0 mL of 0.30 NH4Cl has 0.003 mol of NH4+ and 0.003 mol of Cl-. The 0.10 M sample is a poorer conducted of electricity because it has less ions in solution.
Answer:
0.2 Litres
Explanation:
There are 1000 milliliters in a liter so 200 millimeters is equal to (200/1000) 0.2 litres.
Not quite sure what type of answer you were looking for but I hope this hoped anyway!
