- Given mass density of alcohol is 800 kg/m3
- Given 1 kilogram has a weight of 9.8ย N/kg
Answer = (1) N/m3
ย
Correct Answer
(1) 7840
Explanation
๐พ = ๐ โ ๐
Where:ย
- ๐พ = weight density (in N/mยณ)ย
- ๐ = mass density = 800 kg/mยณย
- ๐ = gravitational acceleration = 9.8 N/kg
๐พ = 800 โ 9.8 = 7840 N/m3
