The percent by mass : 6.3%
<h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
mass of potassium nitrate = 8.4 g⇒solute
- mass of solution = mass of solute+mass of solvent(water)
mass of potassium nitrate + mass of water = 8.4 g + 125 g =133.4 g
Percent by mass of the solute :
C is a chemical property and D is a physical property
Answer:
These thick-haired goats originate in Turkey
Explanation:
and are named after the country's capital, Ankara, historically known as Angora.
Answer: NaF is ionic. NF3 is covalent. SiF4 is ionic. CaF2 is Ionic and NH4F is also ionic. Ionic compounds transfer electrons whereas covalent compounds share electrons hence the word "co". Also, ionic compounds are formed with metal and nonmetal. Where a covalent is with 2 nonmetals. Only ionic compounds would produce fluoride in water because ionic compounds can dissolve in water and covalent compounds cant.
Answer:
The answer to your question is: 98 gr / mole
Explanation:
Molecular weight and molecular mass are synonyms and they referred to sum of the the molecular masses of the elements that form part of a compound. Their units are grams/ mole
In your example we need to sum the molecular mass of the components of sulphuric acid.
Like this:
Hydrogen(H) = 1.008 x 2
Sulphur (S) = 32 x 1 = 32
Oxygen = 16 x 4 = 64
Total = 98 gr / mole
