Approx. 0.140g.

Explanation:

We have 0.1moldm3 NaCl.

Now believe or not, 1dm3=1L, because the prefix deci101

And so,...........1dm3=(1×101m)3

=1×103m31L, because there are 1000L in a m3. A cubic meter is A HUGE VOLUME..........

And so we simply perform the product:

Mass of NaCl=Concentration×Volume×molar mass, NaCl

0.024L×0.1molL1×58.44gmol1=0.140g.
