Please help! Aluminum metal melts at 660 C and boils at 2450 C. Its density is 2.70 grams/cc. Calculate...?

Question

the following:
A. Assuming an ideal gas, the volume occupied by 20.0 kilograms of aluminum vapor at its boiling point and under a pressure of 2280 torr.
B. The volume occupied by 1000. kilograms of metal at 25 C.
C. If the specific heat capacity of aluminum metal is 0.89 Joules per grams-degree C, how many calories of energy are required to heat 10 kilomoles of aluminum from 250 C to 500C.
D. If 13.5 grams of aluminum were dissolved in an excess of concentrated HCI, what volume of hydrogen gas would be released at STP? You may assume that the ideal gas law holds and that the vapor pressure of water is negligible compared to the pressure of the released hydrogen.

Answer 1

Use the gas laws.
