Question

If ρ=3.97⋅g⋅cm−3, what is the mass of an object whose volume is 575⋅cm3?

Answer 1

P=3.97 i.e density=3.97gcm-3

Volume=575cm3

Mass=?

Density =mass/volume

Mass=density x volume

Mass=3.97 x 575 =2282.75

Mass=2282.75g=2.282kg

Answer 2

ρ=Mass

Volume

thus mass=volume×ρ575⋅cm×33.97⋅g⋅cm−3

=over 2 kg of sparkler..
