I need some help:
1) a sheet of aluminum (Al) foil has a total area of 1.000 ft^2 and mass of 3.396g
what is the thickness of the foil in millimeters (density of Al= 2.699 g/cm3) ?
2) a gas company charges 1.50 for 15.0 ft^3 of naturals gas
* if it takes 0.304 ft^3 of gas to boil a liter of water, starting at room temperature (25c),
how much would it cost to boil a 2.3 L kettle of water?
