How many moles are their in 10.6 L os SO2 ?

depends on the temperature and pressure, no?

But at STP, 1 mole fills 22.4 L, so ...

To calculate the number of moles in 10.6 L of SO2, we need to use the ideal gas law equation which states:

PV = nRT

Where:
P = pressure (in atm)
V = volume (in liters)
n = number of moles
R = ideal gas constant (0.0821 L·atm/(mol·K))
T = temperature (in Kelvin)

In this case, we are given the volume (V) of 10.6 L and we need to calculate the number of moles (n).

First, we need to convert the given volume from liters to moles. To do this, we will use the molar volume of a gas at standard temperature and pressure (STP), which is 22.4 L/mol.

10.6 L/22.4 L/mol = 0.4732 mol

Therefore, there are approximately 0.4732 moles of SO2 in 10.6 L of SO2.
