Question

Дано:m(SO2)=28 гНайти: V(SO2)-? N(SO2)-? Моль(SO2)-?

Answer 1

Без моль...подумаю отпишу,а то что-то не вьезжаю

Answer 2

Calculation of V(SO2), N(SO2), and mol(SO2)

To calculate the volume (V), number of moles (N), and molar mass (m) of SO2 (sulfur dioxide), we need to know the mass of SO2 given in the problem.

Given: m(SO2) = 28 g

To find V(SO2), we need to use the ideal gas law equation:

PV = nRT

Where: P is the pressure of the gas (which is not given in the problem), V is the volume of the gas, n is the number of moles of the gas, R is the ideal gas constant (8.314 J/(mol·K)), T is the temperature in Kelvin.

Since the pressure and temperature are not given in the problem, we cannot calculate the volume directly using the ideal gas law.

To find N(SO2), we can use the formula:

N = m / M

Where: N is the number of moles, m is the mass of the substance, M is the molar mass of the substance.

In this case, the molar mass of SO2 is 64 g/mol (32 g/mol for sulfur + 32 g/mol for oxygen). Therefore:

N(SO2) = m(SO2) / M(SO2) = 28 g / 64 g/mol = 0.4375 mol

To find mol(SO2), we can simply use the formula:

mol(SO2) = N(SO2) = 0.4375 mol

Therefore, the answers are: - V(SO2) cannot be determined without the pressure and temperature information. - N(SO2) = 0.4375 mol - mol(SO2) = 0.4375 mol

Please note that the volume of SO2 cannot be determined without additional information.
