C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O
<u>Answer:</u>
(A)
Density = Mass / Volume
So
Mass = Density × Volume


Mole ratio of toluene : Oxygen is 1 : 9

(B)
1 mole of Toluene produces 7 moles of
gas and 4 moles of
Vapour
So the mole ratio is 1 : 11

(C)
1mole contains
molecules

Answer:
1g/ml @ 4 degrees C by definition
Explanation:
Answer: 118.5 grams
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.

where,
n= moles of solute
= volume of solution in ml = 500 ml

moles = 0.75
moles of solute =
0.75 =
mass of
= 118.5 grams
Thus mass of
needed to prepare 500 mL of this solution iis 118.5 grams
