A salt is formed due to the reaction between an oxy acid containing chlorine and a base containing a monovalent metal of atomic mass x. The number of oxygen atoms in one molecule of the acid is more than the corresponding 'ic' acid. Calculate the molecular mass of the salt. View Solution...
Do you ask if 0.25 mole of carbon has the same number of atoms that 0.25 mole of sulfur? Then the answer is yes. Also 0.25 mole of silver has the same number of atoms and so on. Note, that 0.25 mole of oxygen won't have the same number of atoms (hint: what is formula of atmo...

starting and finishing materials are out of balance because there is one magnesium atom on each side, but three hydrogen atoms on the left to two atoms on the right, one chlorine atom on the left to two atoms on the right, and two oxygen atoms on the left to one atom on the right....
Determine the number of atoms of each element in the empirical formula of a compound with the following composition: 68.75 percent C, 10.90 percent H, 20.35 percent O Determine the empirical formula for the compound from percent composition: Cr 19.64 percent and Cl...
A given atom’s atomic number is always equal to its number of protons. Because oxygen has an atomic number of 8, the total number of protons in an oxygen atom is also 8. When describing which isotope an atom belongs to, the total number of neutrons is given to us for computation. At...
