What is the mass, in grams, of 9.000 mL of mercury at 25° C, which has a density of 13.534 g/mL?
bixtya [17]

The mass of the mercury at 25°C is 121.806 g or 121.81 g.

<u>Explanation:</u>

The volume of the mercury = 9.000 mL.

The density of the mercury at 25°C = 13.534\frac{g}{mL}.

The mass of the mercury =?.

density d = \frac{mass}{volume}.

⇒mass= density×volume.

mass=13.534×9.000.

mass=121.806 g or 121.81 g.

How does the water cycle contribute to the "brown ocean" effect?
exis [7]

Answer:

Hurricanes and tropical storms gain their power from heated water evaporating from the ocean.

Explanation:

<h3>Brown Water Effect </h3>
  • The brown ocean effect is an observed weather phenomenon involving some tropical cyclones after landfall. Normally, hurricanes and tropical storms lose strength when they make landfall, but when the brown ocean effect is in play, tropical cyclones maintain strength or even intensify over land surfaces.
