Answer:
specific weight = 49.7 lb/ft^3
specific gravity = 0.797
Explanation:
From Appendix A,
pk = 1.58 slug/ft^3
pea = 1.53 slug/ft^3
volume of kerosene is
Vk = 14 ft^3 - 10 ft^3 = 4 ft^3
The total weight of the mixture is therefore
W = pk g Vk + pea g Vea
= (1.58 slug/ft3) (32.2 ft/s^2) (4 ft^3) + (1.53 slug/ft^3) (32.2 ft/s^2) (10 ft^3)
= 696.16 lb
The specific weight and specific gravity of the mixture are
γm = W
/V
γm = 696.16 lb/ 14 ft^3 = 49.73 lb/ ft^3 = 49.7 lb/ft^3
Sm = γm / γv
Sm = 49.73 lb/ft^3/ 62.4 lb/ft^3 = 0.797
Answer:
0.2 mol
Explanation:
Use the given values to find the molar mass. The molar mass is 40 g/mol.
23 + 16 + 1 = 40
Using the molar mass, convert grams to moles.
(8 g)/(40 g/mol) = 0.2 mol
You have 0.2 mol of sodium hydroxide.
Answer:concentration
Explanation:
In the first, the particles are much more concentrated, or close together, than in the second, where the particles are much more sparse.
D: Schizophrenia. The individual that’s diagnoses with Schizophrenia tends to be disconnected with reality, leading to breakdowns in the world around them. A man sees a crowd of screaming, aggressive ghosts when it’s only a crowd of people waiting for a bus.
