Answer:
Radius = 0.8235 cm
Density = 0.7265 g/mL
Explanation:
Given that the volume = 2.34 cm³
The volume of the sphere = [tex]\frac {4}{3}\times \pi\times r^3[/tex]
Thus,
[tex]\frac {4}{3}\times \pi\times r^3=2.34\ cm^3[/tex]
[tex]\frac {4}{3}\times \frac {22}{7}\times r^3=2.34\ cm^3[/tex]
[tex]r^3=0.5584\ cm^3[/tex]
r = 0.8235 cm
Volume = 2.34 cm³ = 2.34 mL (1 cm³ = 1 mL)
Mass = 1.7 g
Density = Mass/ Volume = 1.7 g / 2.34 mL = 0.7265 g/mL
