To find the mass of the donated blood in grams, we first convert the volume from pints to liters, using the given conversions: 1 pint = 0.473 liters (since 2 pints = 1 quart and 1 quart = 0.947 liters). The volume of donated blood is 0.473 liters. Using the density formula (density = mass/volume), we can find the mass: mass = density × volume = 1.06 × 10^3 kg/m^3 × 0.473 liters × (1 m^3/1000 liters) = 0.502 kg. Converting kilograms to grams (1 kg = 1000 g), we get 0.502 kg × 1000 g/kg = 502 g.

The Average Density of Blood Is 1
