A solution is 12.5% Na3PO, by mass. How many grams of Na3PO4 are there in a 35.9mL solution of Na3PO, if the density of the
solution is 1.10g/mL?

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %

Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?
