ense into clouds, fall to Earth’s surface as precipitation, and then accumulate in a pond. If a horse drinks the water in the pond, which of the following is a likely next step for that water in the hydrologic cycle? A.

The water will be absorbed by the horse's skin and turned into carbon dioxide.
C.
The water will evaporate from the horse's stomach into the air.
D.
The water will leave the horse when the horse sweats or urinates.
The density of He is 1.79 x 10⁻⁴ g/mL In other words in 1 mL there's 1.79 x 10⁻⁴ g of He. To fill a volume of 6.3 L the mass of He required = 1.79 x 10⁻⁴ g/mL * 6300 mL = 11 277 * 10⁻⁴ g Therefore mass of He required = 1.1277 g of He
