Answer:- 3333 g of solution.
Some of the question part is missing here. It would be like, "Determine the mass in grams of each NaCl solution that contains 1.5 g of NaCl.
(i) 0.045% NaCl by mass
Solution:- 0.045% NaCl by mass means 0.045 g of NaCl are present in 100 g of solution. 1.5 g of NaCl would be present in how many grams of solution?
We could solve this using proportions...
(0.045/100) = (1.5/X)
0.045(X) = 1.5(100)
0.045X = 150
X = 150/0.045 = 3333
So, 1.5 g of NaCl is present in 3333 g of solution.

When a phosphate bond breaks, it releases energy, and the ATP turns into ADP
Answer:
hydrogen bonds between water molecules
Explanation:
The hydrogen bonds between water molecules conditions the bulk of its physical property most especially its relatively high boiling point. The hydrogen bond results from the attraction between the oxygen of a water molecule and the hydrogen of another water molecule. The more electronegative oxygen atom causes a distortion and the attraction leads to a strong intermolecular bond between atoms of the water molecules.
Hydrogen bond is a very strong bond and it is responsible for the physical properties of water.

Explanation:
Number of moles of NaOH = 0.3868 L × 1.707 M = 0.660 moles
Reaction of Al^3+ and OH^-
Al^3+(aq) + 3OH^-(aq) -----> Al(OH)3(s)
If 1 mole of Al3+ reacts with 3 moles of OH^-
x moles of Al^3+ reacts with 0.660 moles of OH^-
x = 1 × 0.660/3
x= 0.22 moles
Mass of Al^3+ = 0.22 moles × 27 g/mol = 5.94 g of Al^3+
Co^2+(aq) + 2OH^-(aq) ----> Co(OH)2(s)
1 mole of Co^+ reacts with 2 moles of OH^-
x moles of Co^2+ reacts with 0.660 moles of OH^-
x = 1 × 0.660/2 = 0.33 moles
Mass of Co^2+ = 0.33 moles × 59 g/mol = 19.47 g
