One ton of liquid oxygen and how many cubic meters of oxygen

One ton of liquid oxygen and how many cubic meters of oxygen

Under the standard condition (0 ℃, 101 kPa), the molar volume of gas is 22.4 L / mol, the amount of 1 ton of liquid oxygen is 31250 mol, multiplied by 22.4 L / mol equals 700000 L, that is 700 cubic meters. Under the condition of normal temperature (25 ℃) and 101 kPa, the molar volume of gas is 24.5 L / mol, the amount of 1 ton of liquid oxygen is 31250 mol, multiplied by 24.5

175 liters of liquid oxygen equals several bottles of oxygen

The oxygen cylinder is 40L, but the pressure must be considered. If it is 15MPa, the 40L oxygen cylinder can hold 6000l oxygen

Cube of one plus cube of two What is the cube of N?

Cube of 1 = 1 (1 odd)
Cube of 2 = 3 + 5 (2 odd numbers)
Cube of 3 = 7 + 9 + 11 (3 odd numbers)
……
Cube of n = (square of N-N + 1) + (square of N-N + 3) + +(square of N + n-1) (n odd numbers)
The final answer
[n(n+1)]^2/4
