Question

Calculate the volume occupied by 22.12 g of sodium phosphate at 6.54 atm and 76 degrees Celsius.

Answer 1

Since the substance is not gaseous at the conditions provided, we use density to find volume;

Density $=\dfrac{mass}{volume}$

Thus volume = $\dfrac{mass}{density}$ $=\dfrac{22.12g}{1.62g/cm^3}$ = 13.65cm³
