Answer:
1.1713 moles
Explanation:
RFM of N2O5=108
Moles of N2O5= mass/RFM= 63.25/108=0.5856 moles
Mole ratio of N2O5:NO2= 2:4
Therefore moles of NO2= 4/2*0.5856= 1.1713 moles
The sum is 34.688 m.
If m is a variable, then the m would be attached to 34.688.
0.811 M is the molar concentration of a 252.6 ml aqueous solution prepared with 70.3 g of sugar.
<h3>Define molarity of a solution.</h3>
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution.
Given data:
252.6 mL = 0.2526 L
Next, we shall determine the number of moles of the sugar. This can be obtained as follow:
Molar mass of sugar = 342.30 g/mol.
Mass of sugar = 70.3 g
Mole of sugar =?
Mole =
Mole = 
Mole of sugar = 0.205 mole
Finally, we shall determine the molar concentration of the sugar. This can be obtained as follow:
Mole of sugar = 0.205 mole
Volume = 0.2526 L
Molarity =?
Molarity = 
Molarity = 
Molarity = 0.811 M
Therefore, the molar concentration of the solution is 0.811 M
