If molarity = moles liter , then how many grams of nacl are needed to make 1 liter of a 0.1 m solution? a) 0.0584 g nacl b) 3.246 g nacl c) 5.844 g nacl d) 58.44 g nacl

 The grams  of NaCl   that needed  to make 1L  of a 0.1 M solution  is  

5.845 g (answer C)

 calculation

Step 1: find the  moles of NaCl

moles  = molarity  x  volume  in liters

molarity = 0.1 M =0.1 mol/l

= 1 L x 0.1 Mol/L = 0.1 moles

Step 2: find  the   mass  NaCl

mass =  moles x  molar mass

From  periodic  table   the molar mass of NaCl  = 23 +35.45 =58.45 g/mol

mass= 0.1 moles  x 58.45 g/mol =5.845 g appropriate ( answer C)

To calculate the number of grams of NaCl that would be needed to make 0.1 M of solution we have to calculate;

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
