A spiracle ball of lead has a diameter of 3.5 cm. What is the mass of the sphere if lead has a density of 11.34 g

741.8 kg

Explanation:

mass =  volume  x   density

volume = πr²

   since Diameter = 3.5 cm

   then   radius = 1.75cm

∴ volume  =  π  x  (1.75cm)³

                ≈  16.8369731 cm³

Thus mass  =  16.8369731 cm³  x  11.34  g / cm³

                   =  190.93 g

so what is the problem with your lab report and whats the subject of the lab report? i will you

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
