Answer:
5.46% is the percent by mass concentration of the solution.
Explanation:
Mass of LiBr= 8.2 g(Solute)
Mass of solution = 150 g (Solution)
Mass of solution = Mass of solute + Mass of solvent
Mass of solute < Mass of solvent (Always)
Mass of water = 150 g - 8.2 g = 141.8 g (solvent)
Mass percentage is given as:
5.46% is the percent by mass concentration of the solution.
Answer:
False: <span>The major component in a solution is called the Solvent.
Explanation:
Solutions are the Homogeneous mixtures of two or more substances. Mainly the components are divided into two catogories....
1) Solvent:
The component which is the major or which is present in large amount is called solvent.
Example: In water salt solution water is the solvent.
2) Solute:
</span>The component which is the minor or which is present in less amount is called solute.
Example: In water salt solution salt is the solute.
The volume of 6.00g iron is 0.762 cm^3.
<em>Step 1</em>. Calculate the <em>density of Fe</em>
The <em>specific gravity</em> (SG) of a substance is the ratio of its density to the density of water at 4 °C.
SG = density of substance/density of water.
∴ 7.87 = density of iron/1.00 g·cm^(-3)
Density of Fe = 7.87 × 1.00 g·cm^(-3) = 7.87 g·cm^(-3)
<em>Step 2</em>. Calculate the <em>mass of Fe</em>
Volume of Fe = 6.00 g Fe × (1 cm^3 Fe/7.87 g Fe) = <em>0.762 cm^3</em>
For example, monosaccharides:
C₆H₁₂O₆
aldohexoses
ketohexoses
C₃H₆O₃
aldotrioses
ketotrioses
and many others
Answer:
Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.
