For an aqueous solution of sodium chloride (NaCl) .Determine the molarity of 3.45L of a solution that contains 145g of sodium
worty [1.4K]
Molar mass NaCl = 58.44 g/mol

number of moles:

mass NaCl / molar mass

145 / 58.44 => 2.4811 moles of NaCl

Volume = 3.45 L

Therefore :

M = moles / volume in liters:

M = 2.4811 / 3.45

M = 0.719 mol/L⁻¹

hope this helps!

1 mole of nacl(s) has a greater entropy than 1 mole of nacl(aq). true or false g
Svetradugi [14.3K]
It  is  false   that  1  mole  of  nacl(s)  has  a  greater  entropy  than   1  mole  of  nacl (aq).  

  this  is  because    nacl(aq)   is  in  aqueous  state  while  nacl(s)  is  in  solid  state.  Nacl(aq)  has  greater  entropy  than  nacl(s)  because    in 
aqueous   state  their   is  increase  in  entropy. the  entropy   of  the  two  ions  in  water  has   greater  entropy  than  the  solid   nacl.
