Answer:
9g
Explanation:
Since..., Density = mass/volume
;Firstly calculate the volume change of the water when the metal is placed in,
;Volume = 26.47 - 21.25
;Volume = 5.22 mL
Hence the mass of the ore;
; Making mass the subject of formula in the above equation,
Mass = Density × Volume
; Mass = 1.72 × 5.22
; Hence the mass = 8.9784
= 9g
Density = mass / volume
Density = (45g) / (9 [volume units])
Density = 5g / [volume unit]
There was no specification on the units of volume. However, whatever it may be, just replace the square brackets with the value and your units will be correct.
