HEAT OF VAPORIZATION Q=mx H,
If the heatyaporization of isopropyl alcohol is measured at 702 joules/gram and it requires 596,700 joules of energy to vaporize a sample, how many grams of isopropyl alcohol were in the sample? ​

How many grams of aluminum will there be in 98g of al2o3?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
