Question

Масса CO2=13,2г, найти оъбем (на листочке) ​

Answer 1

Ответ:

Объяснение:

M=(12+16*2)*10^-3=44*10^-3 кг/моль

m=13,2 г=13,2*10^-3 кг

n=m/M=(13,2*10^-3)/(44*10^-3)=0,3 моль

n=V/Vm

V=n*Vm=0,3*22.4=6,72 л= 0.00672 м^3

Answer 2

Calculating the Volume of CO2

To calculate the volume of CO2, we can use the ideal gas law equation, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

Given: - Mass of CO2 (m) = 13.2 g - Molar mass of CO2 = 44.01 g/mol (from the periodic table)

We can first calculate the number of moles of CO2 using the formula: n = m / M where: - n = number of moles - m = mass of the substance - M = molar mass of the substance

Calculating the Number of Moles: Using the given mass of CO2 and its molar mass: n = 13.2 g / 44.01 g/mol n ≈ 0.3 moles

Now, we can use the ideal gas law to calculate the volume of CO2. However, we need additional information such as the pressure and temperature to get an accurate result. If you have the pressure and temperature, we can proceed with the calculation.
