4NH3+5O2=4NO+6H2 How many grams of hydrogen can be produced from 350 grams of oxygen?
Molar mass of hydrogen as 2g/mol
Molar mass of Oxygen as 32

When the speed of the bottle is 2 m/s, the average maximum height of the beanbag is m.

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.

Helium decays to form lithium. which equation correctly describes this decay?
