A 200g bottle has a mass of 340g when filled with water and 344g when field with blood plasma. what is the density of plasma?
140 g of blood has the same volume as 144 g of blood.
Blood's density must be 144/140 times that of water, or 1.029 g/ml
To find the density of plasma, we need to use the formula for density:
Density = Mass / Volume
First, let's calculate the volume of the bottle:
Volume = Mass of water - Mass of empty bottle
Given:
Mass of water = 340 g
Mass of empty bottle = 200 g
Volume = 340 g - 200 g = 140 g
Next, let's calculate the density of plasma:
Density of plasma = Mass of plasma / Volume
Given:
Mass of plasma = 344 g
Volume = 140 g
Density of plasma = 344 g / 140 g = 2.457 g/mL
Therefore, the density of plasma is 2.457 g/mL.
To find the density of the plasma, we need to use the formula:
Density = Mass / Volume
Given that the mass of the bottle is 200g, the mass of the bottle filled with water is 340g, and the mass of the bottle filled with blood plasma is 344g, we can calculate the density of plasma using the following steps:
1. Calculate the mass of the water:
Mass of water = Mass of bottle filled with water - Mass of empty bottle
= 340g - 200g
= 140g
2. Calculate the mass of the plasma:
Mass of plasma = Mass of bottle filled with plasma - Mass of empty bottle
= 344g - 200g
= 144g
3. Calculate the volume of the plasma:
Since the density of a substance is calculated by dividing its mass by its volume, we need to find the volume of the plasma. However, we know that the volume of the bottle remains constant, so we can ignore the volume and directly use the ratio of the masses.
4. Calculate the density of the plasma:
Density of plasma = Mass of plasma / Volume of plasma
= Mass of plasma / Volume of bottle
= 144g / 200g
= 0.72 g/mL
Therefore, the density of the blood plasma is 0.72 g/mL.
