There is 40 g of sugar in a 500 ml bottle of lemon juice
<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.
the concentration of sugar in lemon juice :
So for 500 ml juice :
This is a incomplete question. The complete question is:
It takes 348 kJ/mol to break a carbon-carbon single bond. Calculate the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon. Round your answer to correct number of significant digits
Answer: 344 nm
Explanation:
E= energy = 348kJ= 348000 J (1kJ=1000J)
N = avogadro's number =
h = Planck's constant =
c = speed of light =
Thus the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon is 344 nm
Answer: B. 0.6125 m
For spherical concave mirror:
Height of the object,
Height of the image,
Object distance, u=-0.7 m
we need to find the distance of the image, v.
These are related by the following formula:
Insert the values:
Hence, option B is the correct.
