A toxicity is answer for that question
The percentage of dissolved salt in saltwater
is 3.5%. We are given the amount seawater sample. <span>We would just multiply the two values together.
750 g (0.035) = 26.25 g NaCl
26.25 g NaCl ( 1 mol / 59.44 g ) ( 1 mol Na / 1 mol NaCl ) ( 22.99 g / 1 mol ) = 10.15 g Na
Hope this answers the question. Have a nice day.</span>

Explanation:
Given parameters:
Density of ebony wood = 1.174g/ml
Mass of wood = 2.1549lb
Unknown:
Volume of the wood in quarts = ?
Solution:
Density is defined as the mass per unit volume of a substance.
Mass is the quantity of matter the wood contains.
Volume is the space it occupies.
To solve this problem, convert the mass form pounds into grams and plug into the density equation to find volume.
Then convert the volume from mL to quarts.
Density =
Volume =
1 pound = 453.592g
2.1549 lb = 2.1549 x 453.592 = 977.5g
Volume = = 832.6mL
1 quart = 946.353mL
Therefore 832.6mL x = 0.88qt
