How many moles of al3+ ions are in 1.25 moles of al2o3

What is the molar mass of a gas that has density of 2.054 g/l

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
