Answer:
Solution is 4.67% by mass of salt
Explanation:
% by mass is the concentration that defines the mass of solute in 100g of solution.
In this case we have to find out the mass of solution with the data given:
Mass of solution = Mass of solute + Mass of solvent
Solute: Salt → 14.2 g
Solvent: Water → 290 g
Solution's mass = 14.2 g + 290g = 304.2 g
% by mass = (mass of solute / mass of solution) . 100
(14.2 g / 304.2g) . 100 = 4.67 %
Answer is: l<span>ight-dependent reactions and l</span>ight-independent reactions (dark or carbon reactions or <span>Calvin cycle).
</span>In photosynthesis (<span>convert </span>light<span> energy into </span>chemical energy)<span>,
the carbon in carbon(IV) oxide is being reduced to form glucose.
</span>The pigment chlorophyll<span> absorbs one </span>photon<span> and loses one </span>electron (it passed throw <span>an </span>electron transport chain) in the light-dependent reactions.
<span>The </span>enzyme RuBisCO takes carbon(IV) oxide i<span>n the </span><span>light-independent reactions.</span><span>
