The density of helium is 0.17 g/L. What Is the mass of helium in a 5.4 L helium balloon? (2 sig figs) *
ioda

Answer:

The correct answer is 0.92 g

volume= 5.4 L

density= 0.17 g/L

Thus, to calculate the mass of helium:

mass= density x volume = 0.17 g/L x 5.4 L= 0.918 g ≅ 0.92 g

how does the increased salinity of the dead sea due to fertiliser industry impact the microscopic organisms that live there​
polet [3.4K]

In times of flood, the salt content of the Dead Sea can drop from its usual 35% to 30% or lower.
