Mass number of Silver: The element Silver (Symbol Ag) has the Atomic Number of 47. The number of protons in atom of silver is therefore 47. Silver has the Atomic Mass weight of 107.87. Round to the nearest whole number. The mass number of silver is therefore 108.
Answer:
8.77 grams NaC
Explanation:
To find the mass of NaCl, you need to (1) use the molarity equation to find moles, then (2) calculate the molar mass of NaCl (via the periodic table), and then (3) convert moles NaCl to grams (via molar mass). The final answer should have 3 sig figs because the given values also have 3 sig figs.
(Step 1)
Molarity (M) = moles / volume (L)
0.250 M = moles / 0.600 L
(0.250 M) x (0.600 L) = moles
0.150 = moles
(Step 2)
Molar Mass (NaCl): 22.99 g/mol + 35.45 g/mol
Molar Mass (NaCl): 58.44 g/mol
(Step 3)
0.150 moles NaCl 58.44 g
