8 multiplied by 6 equals 48
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
Force or weight Force= mass X acceleration gravity is an acceleration (9.8m/s2) Weight = mass X acceleration due to gravity
nM=m moles of solid multiplied by Molar mass (Atomic mass on periodic table) = Mass of solid
