The molar mass of sodium acetate (NaCH3COO) can be calculated by summing the atomic masses of its constituent elements. Here's the breakdown:
Na (sodium) has an atomic mass of 22.99 grams/mol. C (carbon) has an atomic mass of 12.01 grams/mol. H (hydrogen) has an atomic mass of 1.01 grams/mol. O (oxygen) has an atomic mass of 16.00 grams/mol.
Since there is one sodium (Na), one carbon (C), three hydrogens (H), two oxygens (O), and one acetate group (CH3COO-) in sodium acetate, we can calculate its molar mass as follows:
Molar mass of NaCH3COO = (1 * Na) + (1 * C) + (3 * H) + (2 * O) = (1 * 22.99) + (1 * 12.01) + (3 * 1.01) + (2 * 16.00) = 22.99 + 12.01 + 3.03 + 32.00 = 70.03 grams/mol
Therefore, the molar mass of sodium acetate (NaCH3COO) is approximately 70.03 grams/mol.
