How do I work out the density of HCI at 600 celsius ?

Thanks

I assume you mean the gas, hydrogen chloride.

PV=nRT
density is mass/volume
n/V=P/RT
mass/V= molmass*Pressure/RT

I would use PV = nRT and rework it a little

n = g/M where M is molar mass.
PV = (g/M)RT, then
PVM = gRT and
PM = gRT/V where g/V is the density and solve for g/V = density = PM/RT. Check my algebra.

Thank you guys I will try both suggestions

OK to try both I suppose but aren't both the same? (They are the same formula!)

To calculate the density of hydrochloric acid (HCl) at 600 degrees Celsius, you would need to know the relevant temperature and density data. Different concentrations of HCl have varying densities, so you would also need to specify the concentration of the acid solution.

Here's a general procedure to determine the density at a given temperature:

1. Determine the concentration of the hydrochloric acid solution. For example, is it a 1 Molar (1M), 2M, or a different concentration?

2. Find a reliable source, such as chemical handbooks or scientific databases, that provide the density values for the specific concentration of HCl at different temperatures.

3. Look up the density of hydrochloric acid at 600 degrees Celsius for the desired concentration. Make sure the density values are given in the appropriate units, such as grams per milliliter (g/mL).

4. If the density is provided in a different unit, convert it to the units you prefer using appropriate conversion factors. For example, you might need to convert grams per milliliter to kilograms per cubic meter or pounds per gallon.

5. Plug in the obtained density value to calculate the density of HCl at 600 degrees Celsius for the given concentration.

Please note that hydrochloric acid is highly corrosive and can be hazardous. Make sure to follow proper safety procedures when handling it and ensure you have adequate training and safety measures in place.
