A student sets up the following equation to solve a problem in solution stoichiometry. (The ? stands for a number the student is going to calculate.) Enter the units of the student's answer. (0.34 L)(1 mL/10^-3 L) (0.58 g/mL)/(64.63 g/mol) = ?

Answer:

The units are moles.

Explanation:

Hello!

In this case, considering the following dimensional analysis operation:

[tex]0.34L*\frac{1mL}{1x10^{-3}L} *\frac{0.58g}{1mL} *\frac{mol}{64.63g}[/tex]

We can see liters, milliliters and grams are cancelled out as they are put at both denominators and numerators; it means that the final units are moles.

In addition, the result should be:

[tex]3.1mol[/tex]

Which has two significant figures as the data is given with two significant figures.

Best regards
