Answer:
Blood capillaries
Explanation:
The walls of capillaries are just one cell thick. Capillaries therefore allow the exchange of molecules between the blood and the body's cells - molecules can diffuse across their walls. This exchange of molecules is not possible across the walls of other types of blood vessel.
There are two general classifications of mixtures: homogeneous mixture and heterogeneous mixture. Since sugar dissolves in water, this is a homogeneous mixture. In other words, it is called as a solution. Furthermore, there are 3 classifications of solution: unsaturated, saturated and supersaturated. Since only a few are added to the water and all of them dissolved, this is an unsaturated homogeneous mixture.
Answer:
Liquid: 38.7 g x 1 ml/0.865 g = ml of liquid
Vol of solid = 80.0 ml - ml of liquid
mass of solid = vol of solid x 2.75 g/ml
(100. g)
Explanation:
you can use this as a eg for this question
Mol (n) = 29.0
molar mass (M) Na = 23 g/mol
mass (m) = ?
m = nxM
m = 29.0x23
m = 667 g
mol (n) = 29.0
molar mass (M) Cl = 35.5 g/mol
mass (m) = ?
m = nxM
m = 29.0x35.5
m = 1029.5 g
