If the sugar makes up 25% of the solution, that means the water makes up 75%, or 3/4, of the solution.
Set up a proportion to solve:
Cross multiply:
Therefore, there are 354 grams of water in the solution.
Answer:
Josue
Explanation:
J.J Thompson proposed the plum pudding model of the atom. In his proposition, the atom is a sphere of positive charges into which negative charges were embedded. This model of the atom did not significantly contribute to our present day understanding of atomic structure.
On the other hand Ernest Rutherford laid out the foundation for a more accurate understanding of atomic structure in his nuclear model of the atom. According to Rutherford, the atom consists of a positively charged massive core called the nucleus around which electron move in orbits. His idea was akin to the solar system with the sun at it's core and planets moving around the sun in orbits.
This his idea of the nuclear theory was held as fundamentally correct by Neils Bohr's model of the atom. Hence, his nuclear theory of the atom was a significant milestone in our present day understanding of atomic structure.
In the dark waters just below the photic zone, because of cellular respiration, the concentration of dissolved carbon dioxide is higher relative to dissolved oxygen.
In cellular respiration living organisms use oxygen and release carbon dioxide, because there is little or no light there is no photosynthesis and oxygen is little produced.
To solve for the solubility of this compound:Cu ^ + 2 + CO3 ^ -2 = [x] [x] = x^2 1.4 x 10 ^ -10 = x^2 x = 1.1832 x 10 ^ -5 1.1832 x 10 ^ -5 moles/ L x 123.526 g/mol (molar mass) is equals to 1.5 x 10 ^-3 g/L is the solubility of this compound - CuCO3.
