The density of blood is 1050 kgm3 what is this density in gcm3?

Answer 1

One kilogram equals 1000 grams. And one meter being equal to 100 centimeters, one cubic meter equals one million cubic centimeters. Hence it is clear that one kilogram per cubic meter equals one thousandth gram per cubic centimeter. So blood density which is 1050 kg per cubic meter equals 1.05 grams per cubic centimeter. As 1000kg of pure water @ 4°C = 1 cubic metre, those materials under 1000kg/cubic metre will float; more dense will sink ie. those materials with a specific gravity more than 1. As milk is denser than pure water 1 cubic metre of milk @15°C will weigh 1020 kg to 1050 kg. The density of an object is the ratio of its mass to its volume. Density can also be expressed as specific gravity. The density of seawater at the surface of the ocean varies from 1,020 to 1,029 kilograms per cubic meter." 1020--1029 kg/m3 Seawater is usually some 3.5 percent heavier than fresh water because it contains about 35 pounds of salts in each 1,000 pounds of water. It is customary to report the density of seawater in equivalent to "grams per litre excess over one kilogram," designated by the symbol σ. In this notation, the specific gravity of 1.025 is expressed as σ of 25."
