An oceanographer collects $2.50 \text{ m}^3$ of seawater with a salinity of $35.0 \text{ PSU}$ (which is approximately $35.0 \text{ g}$ of dissolved salts per kilogram of seawater). If the density of this seawater sample is $1.025 \text{ g/cm}^3$, calculate the total mass of dissolved salt in kilograms.
