Question

Визначте, який обєм (н.у.) займає кисень масою 10 г.?

Answer 1

Объяснение:

V(O2)=n(O2)•Vm=m/M•Vm=(10•22.4)/(16•2)=7л

Answer 2

Calculating the Volume of Oxygen

To calculate the volume of oxygen, we can use the ideal gas law, which states that the volume of a gas is directly proportional to the number of moles of the gas and the temperature, and inversely proportional to the pressure. The ideal gas law is given by the equation:

PV = nRT

Where: - P = pressure - V = volume - n = number of moles - R = ideal gas constant - T = temperature

Given: - Mass of oxygen = 10 g - Molecular weight of oxygen (O2) = 32 g/mol

We can calculate the number of moles of oxygen using the formula:

moles = mass / molecular weight

Substitute the given values: moles = 10 g / 32 g/mol

Now, we can use the ideal gas law to calculate the volume of oxygen.

Calculation

Using the ideal gas law, we can calculate the volume of oxygen. The ideal gas constant (R) is 0.0821 L·atm/(K·mol) at standard temperature and pressure.

Let's calculate the volume of oxygen using the given information.

V = (nRT) / P

Substitute the given values: V = (moles * R * T) / P

Given: - R = 0.0821 L·atm/(K·mol) (ideal gas constant) - T = temperature (not provided) - P = pressure (not provided)

Since the temperature and pressure are not provided, we are unable to calculate the exact volume of oxygen without these values.

Therefore, without the specific temperature and pressure, we are unable to provide the exact volume of oxygen.
