Answer:
Molarity of
solution is 0.612 mol/L
Explanation:
Number of moles of a substance = (mass of substance)/(molar mass of the substance)
Molar mass of
= 214 g/mol
So, 562 g of
=
moles of
= 2.63 moles of 
Molarity of a solution = (number of moles of solute in solution)/(total volume of solution in liter)
Here solute is
and solvent is water
Total volume of solution is 4.30 L
So, molarity of
solution =
= 0.612 mol/L
The answer is D. A compound
super easy to just google that:)
Answer:
i) 0,7 molH20/s
ii)11,2 g O/s
iii)1,4 g H/s
Explanation:
i) To find the molar flow rate of water, we just convert the mass of water to moles of water using its molecular weight(g/mol) and changing to the proper units (lb to grames and hours to seconds):

ii) Now we just consider the oxygen in the water stream (for 1 mole of water there is 1 mole of oxygen):

iii)Just considering the hydrogen in the stream (for 1 mole of water there is 2 moles of hydrogen):
