Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one set of units to another set of units. In this question, we need to convert the flow rate from Sverdrups (sv) to milliliters per minute (mL/min). Understanding how to convert between different units of volume and time is essential for solving the problem.

Conversion Factors

Volume and Flow Rate

Flow rate is a measure of the volume of fluid that passes through a given surface per unit of time. In this case, the Gulf Stream's flow rate is given in Sverdrups, which represents cubic meters per second. Recognizing the relationship between volume, flow rate, and time is crucial for accurately calculating the flow in different units.

A calibrated flask was filled to the 25.00 mL mark with ethyl alcohol. By weighing the flask before and after add-ing the alcohol, it was determined that the flask contained 19.7325 g of alcohol. In a second experiment, 25.0920 g of metal beads were added to the flask, and the flask was again filled to the 25.00 mL mark with ethyl alcohol. The total mass of the metal plus alcohol in the flask was determined to be 38.4704 g. What is the density of the metal in g/mL?
