Answer:
Density of block of gold is <em>3.5 g/cm³.</em>
Explanation:
Given data:
Volume of block = 1000 mL
Mass of block = 3.5 kg (3.5×1000 = 3500 g)
Density of block = ?
Solution:
Density of substance is calculated by dividing the mass of substance over its volume.
Formula:
d = m/v
d = 3500 g/ 1000 mL
d = 3.5 g/mL
or
d = 3.5 g/cm³ (1ml = 1cm³)
