A student ENCN $281$ sampled his water to determine the solids. He made a variety of

measurements but then carelessly mixed up the data sheets such that he now has to

match the numerical data with the measurements. The measurements are:

Weight of evaporating dish $=51\mathrm{.}4681$ grams. Assume ${}_{\text{s}\text{o}\text{l}\text{'}\text{n}}=1k\frac{g}{L}$

Weight of dish plus liquid sample $=69\mathrm{.}4564$ grams.

Weight of dish plus sample after combustion at $550C=52\mathrm{.}5464$ grams.

Weight of dish plus sample after drying at $105C=53\mathrm{.}9421$ grams.

Sort the data out for him and calculate the total solids $m\frac{g}{L}$ and the

total volatile solids in $m\frac{g}{L}.$

Which of the values is correct $(\frac{g}{L}?$
