Question

Який об,эм щаймпють 10г кисню за н.у?​

Answer 1

Відповідь:

7 л.

Пояснення:

V = n × Vm

n = m/M

M (O2) = Mr (O2)= 16×2 = 32

n = 10/32 = 0.3125

V = 0.3125 × 22.4 = 7

Answer 2

Oxygen's Molar Volume at STP

The molar volume of a gas at standard temperature and pressure (STP) is the volume occupied by one mole of the gas at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere. For oxygen, the molar volume at STP can be calculated using the ideal gas law.

Molar Volume of Oxygen at STP: The molar volume of oxygen at STP is approximately 22.4 liters per mole.

This value is derived from the ideal gas law, which states that at STP, one mole of any gas occupies a volume of 22.4 liters.
