Answer:
Yes, this answer is correct.
Explanation:
Absolute zero is -273.15 degrees celsius
T= Tc+273.15
T is the kelvin temperature
Tc is the temperature in degrees celsius
substitute;
T= -273.15 + 273.15
T=0 K

Convert mole to gram by multiplying the molar mass of sodium
0.500mol Na x 22.990g = 11.495g of Na
In order to find molarity, you must first find the number of moles that was dissolved.
Now, Moles = Mass ÷ Molar Mass
⇒ Moles of NaCl = 2.922 g ÷ 58.44 g/mol
= 0.05 moles
∴ the Molarity of the NaCl is 0.05 M [Option 1]
