<span>2 C6H6 + 15 O2 = 12 CO2 + 6 H2O
</span>
2 moles C6H6 -------------------- 6 moles H2O
8.73 moles C6H6 --------------- ( moles H2O)
( moles H2O) = 8.73 x 6 / 2
( moles H2O) = 52.38 / 2
= 26.19 moles of H2O
Molar mass H2O = 18.00 g/mol
1 mole -------------- 18.00 g
26.19 moles ----- ( mass of H2O)
mass of H2O = 26. 19 x 18.00 => 471.42 g of water
hope this helps!

PV = nRT
R = 0.0821 L * atm / mol * K
(ideal gas constant)
First, convert 735 torr to atm. Divide by 760.
(1 atm = 760 torr)
735 torr * 1 atm / 760 torr = 0.967 atm
Then, convert 37 C to Kelvin. Just add 273.
37 C = 310K
n = PV / RT
= (0.967)(2.07) / (0.0821)(310)
= 0.0786 mol
<span>0.0786 mol * 6.02 * 10^23 molecules / 1 mol = 4.73 * 10^22 molecules </span>
The volume in millilitres of 2.37M potassium hydroxide that contains 9.29g of solute is 70mL.
<h3>How to calculate volume?</h3>
Volume of a solution can be calculated from the molarity, which is the concentration of a substance in solution, expressed as the number moles of solute per litre of solution.
Molarity = no of moles ÷ volume
no of moles = mass ÷ molar mass
Molar mass of pottasium hydroxide (KOH) = 56.1056 g/mol
moles = 9.29g ÷ 56.1056 g/mol = 0.166moles
2.37 = 0.166/V
V = 0.166 ÷ 2.37
V = 0.07L
Volume in millilitres = 70mL
Therefore, 70mL is the volume of the pottasium hydroxide solution.
