A perfect sphere of aluminum metal with a diameter of 4.56x10^-2 m reacts with 3.80L of 5.25M hydrochloric acid. the products are an aluminum chloride solution and hydrogen gas. When the gaseous product is collected in a 2.00L vessel at 25 degrees C, the pressure was observed to be 4.64x10^4 torr.
Note: The density of Al is 2.70 g/cm^3; the density of aluminum chloride is 2.48 g/cm^3
