Compare the density of the two solutions.
18 g ÷ 6 L = 3 g/L
24 g ÷ 12 L = 2 g/L
Solution A is more concentrated because it has more grams solute per liter of solution.
The correct answer among the choices given is option B. The one that describes a proper use of eyeglasses is that using diverging lenses to help a nearsighted person by moving the image from in front of the retina to the retina. For this, t<span>he lenses will diverge the light before it reach the eye and aim it to the retina, correcting our nearsighted visual.</span>

In order to determine the number of moles of the given volume of Ar, divide the given volume by the molar volume of an ideal gas,
So you have a volume of 6
6.5L / 22.710 L/mol
L is eliminate .
6.5/ 22.710 L/mol
= 0.286 mol
Using the older STP values of 0
C or 273.15 K
, and pressure of 1 atm
, molar volume is 22.414 L/mol
6.5L /22.414 L/mol
.= 0.289 mol
Since the ions cannot move, ionic solids are non-conductors of electricity. When the solid is melted to a liquid, however, the ions are free to migrate. Therefore, ionic liquids are good conductors of electric current. A conductor is a substance capable of transmitting electricity and/or heat.
You are not belive that many years ago approximate in 1900 century the people made plastic my milk this plasticity then use for making ornaments beads jewelry buckls pens and many more decorative things.
Take a thermos and add one cup of milk and heat it after heating it add 3,4 spoon of vinagar and place it aside for sometime until you will see the milk turns to plastic like shape this was very useful method for making plastic.
