Insulation wraps because independent is the variable you are changing to affect the dependent variable (what you are measuring)
name= calcium
atomic mass= 40.078 atomic mass unit
no of protons= 20
no of electrons=20
Use the density to convert volume into mass.
since the density is in g/ml and the volume was given in Liters, we need to first convert the Liters into mililiters. just multiply by 1000 or move the decimal three times.
0.1200 Liters= 120.0 mL
120.0 mL (0.8787 grams/ 1 mL)= 105 grams
