How many times more massive is a copper atom than an aluminum atom?

Sugar is dissolved in water. which is the solute? sugar neither both water

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

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.
