You can have a solution of hydrogen peroxide that might say 10% that means that 10% per mass of the hydrogen peroxide solution is the hydrogen peroxide the rest is water.

concentration is the amount of mass in the solution eg 5gdm-3

hope that helps

Find the density of an object that has a mass of 5 kg and a<br> volume of 50 cm3.
iren2701 [21]
  • Mass=5kg=5000g
  • Volume=50cm^3

\\ \rm\longmapsto Density=\dfrac{Mass}{Volume}

\\ \rm\longmapsto Density=\dfrac{5000}{50}

\\ \rm\longmapsto Density=100g/cm^3

The nucleus of a Helium atom has a charge equal to twice the proton's charge. Let FN denote the magnitude of the force the Heliu
pshichka [43]

FN = Fe

Explanation:

Although the charge aren't the same, it should be equal to the magnitude of the forces. The coulomb force governs between both the nucleus and the electron, which is equal to the charge element.

The FN and Fe magnitudes somehow have to be equal, because the ordering does not apply in the multiplication.

There is a much more specific explanation, however, for such powers to be equivalent: they are the relationship pair of the third law of Newton, which has the same in scale and the direction opposite .

All naturally occuring polysaccharide have one terminal residue a free anomeric carbon why do these polysaccharide not give a po
UNO [17]

Answer:  The concentration of reducing ends is too small to detect.

Explanation:

The reducing sugar can be defined as the sugar that is capable of acting as a reducing agent because it possesses an aldehyde group and a ketone group. Some polysaccharides are reducing sugars but all the monosaccharides are reducing sugars. The polysaccharide with reducing sugars do not give a positive test for reducing sugars because the concentration or amount of reducing ends is too small to detect.
