Answer:
Most organic compounds contain carbon and <u>hydrogen</u>.
Explanation:
Organic compounds are class of compounds which mainly constitute carbon and other elements like hydrogen, oxygen, nitrogen and sulfur etc.
In these compounds hydrogen is essentially present along with carbon as both make the basic organic class of compounds namely, Alkanes (saturated hydrocarbons), Alkenes and Alkynes (unsaturated hydrocarbons).
While remaining classes of organic compounds are derived from these three classes of hydrocarbons. Therefore, we can conclude that organic compounds are basically made up of carbon and hydrogen.
Density = Mass/Volume
d= 5 / 4.5
Answer:
Solution is 4.67% by mass of salt
Explanation:
% by mass is the concentration that defines the mass of solute in 100g of solution.
In this case we have to find out the mass of solution with the data given:
Mass of solution = Mass of solute + Mass of solvent
Solute: Salt → 14.2 g
Solvent: Water → 290 g
Solution's mass = 14.2 g + 290g = 304.2 g
% by mass = (mass of solute / mass of solution) . 100
(14.2 g / 304.2g) . 100 = 4.67 %
