Question

if you have 300 mL of 15 m NaCl how many ml of 0.25 M NaCl can you make​

Answer 1

M1V1=M2V2,. 15=M1, V1=300, M2=0.25 ,V2=?,. 15×300=0.25×V2, after solving it V2=18000ml. or 18 lit

Answer 2

Explanation:

moles = M×volume

=15×0.3×0.3×0.3

=0.405

volume = moles/M

=0.405/0.25

in litter = taking cube root of 0.405/0.25

convert the above value into ml you will get the answer
