Ocean Density and Its Correlation with Ocean Temperature and Salinity

Mass and volu...

Question

Mass and volume of an object are measured as 4.237g and 2.5 cm3. Calculate its density upto correct significant figure

Open in App

Solution

Density = mass/volume

$D e n s i t y = \frac{4.237 g}{2.5 c m^{3}} = 1.6948 g / c m^{3} = 1.7 g / c m^{3} T h u s, t h e d e n s i t y i s r e p o r t e d t o t w o s i g n i f i c a n t f i g u r e s o n l y .$
