How many liters of formaldehyde is obtained by the catalytic oxidation of methanol if 96 g

How many liters of formaldehyde is obtained by the catalytic oxidation of methanol if 96 g of oxygen is consumed for this reaction?

1. To solve, write down the equation:
m = 96 g. X l. -?
2СН3ОН + О2 = 2СН2О + 2Н2О – formaldehyde was obtained in the process of catalytic oxidation;
2. Calculations:
M (O2) = 32 g / mol;
M (CH2O) = 30 g / mol.
3. Determine the amount of O2:
Y (O2) = m / M = 96/32 = 3 mol.
4. Proportion:
3 mol (O2) – X mol (CH2O);
-1 mol – 2 mol from here, X mol (CH2O) = 3 * 2/1 = 6 mol.
5. Find the volume of the product:
V (CH2O) = 6 * 22.4 = 134.4 liters.
Answer: in the process of oxidation, formaldehyde with a volume of 134.4 liters was formed.
