Answer:
480
Step-by-step explanation:
Density of a substance is mass per unit volume, Mathematically expressed as
d=m/v
Making m the subject of the formula then
m=dv
Here, d is the density, m is the mass of helium and v is the volume of helium
Given density as 0.1685 kg/m³ and volume as 2850 m³ then jts mass will be equivalent to
Mass=2850m³*0.1685kg/m³=480.225 kg
Rounding off to the nearest whole number, the mass is approximately 480 kg
