Is the solution isotonic, hypertonic, or hypotonic?
Osmotic pressure for non-electrolytic solutes is given by

$$\pi = CRT$$

where $C$ is the effective concentration of all the solutes. In our case, with multiple solutes, we simply add all their concentrations to obtain the effective concentration. This gives us

$$
\begin{align}
\pi_\mathrm{cell} &amp;= 0.05RT\\
\pi_\mathrm{environment} &amp;= 0.03RT
\end{align}
$$

Since $\pi_\mathrm{environment} &lt; \pi_\mathrm{cell},$ The environment solution is hypotonic.
