If you start with 4.0 grams of sodium flouride (naf), how many grams of magnesium flouride (mgf2) will be produced? the molar mass of naf is 42g/mole and the molar mass of mgf2 is 62g/mole.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?

If 16.00g of hydrogen gas reacts with 126.73g of oxygen, how many grams of water are yielded? (both reactants are completely consumed in the reaction.)
