Question

a .0400M NaCl solution was formed when 32g of NaCl was dissolved in water. What was the total volume of the solution formed?

7.20 L
9.80 L
13.7 L
18.1 L

Answer 1

convert 32g NaCl to moles

then solve

0.04M NaCl solution = moles NaCl / (x L of solution) for x

Answer 2

ok so NaCl is 58.4 g/mol, now what?

Answer 3

as per my instructions, convert 32 g of NaCl to moles

Answer 4

32g / (58.4 g/mol) gives moles NaCl
then plug into the equation and solve for x

Answer 5

ok so i got .5479 when dividing 32/58.4. but what’s the equation? sorry i’m a little slow, haha !

Answer 7

ok thank you!! i’ll try and solve it now :)

Answer 8

in case you get back to this

0.04M NaCl solution = moles NaCl / (x L of solution) for x

x = 32g / (58.4 g/mol) / (0.04) = 13.7L

Answer 9

thank you!! that’s what i got too :)
