Dead Sea water

When Vera visited the Dead Sea, she took a bowl with sand, pebbles, and water from the sea as a souvenir. The water in the bowl weighed 400 g. How many deciliters of water did she carry away from the sea? The density of salt water in the Dead Sea is 1.240 kg/l

Final Answer:

V =  3.2258 dl

Step-by-step explanation:

$$\begin{gathered} m=400\text{g}\to \text{kg}=400:1000\text{kg}=0.4\text{kg} \\ \rho =1.24\text{kg/l} \\ \rho =m/V \\ {V}_1=m/\rho =0.4/1.24=\frac{10}{31}\doteq 0.3226\text{l} \\ V=V_1\cdot 10=0.3226\cdot 10=3.2258\text{dl} \end{gathered}$$
