Answer:
for those whos question asked them to round to the nearest whole number the answer is 456
Explanation:
The weather balloon contains 456.3 kilograms of helium.
How are the density, volume and mass of a substance related?
Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kg
density of substance = d kg/m³
volume of that substance = v m³
Then, they are related as:
[tex]Density = \frac{mass}{volume}[/tex]
For the given case, we are given that:
Volume of balloon = volume of helium it contains = 2600 m³ = m
Density of helium it contains = 0.1755 kg/m³ = d
Let its mass be m, then:
Density of helium it contains = 2600 × 0.1755
= 456.3.
Hence, the weather balloon contains 456.3 kilograms of helium.
