It is the Answer to your question.
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
--------------------------- x ------------------- = 8.77 grams NaCl
1 mole
It mostly because they're so reactive and if they were in their pure form and touched water they would have a very violent reaction. They also want to be more stable so they look for more electrons and quickly bond.
