Number of moles of reactant = 0.2mol
Molar mass of product = 122.12g
Number of moles of product = given mass/ molar mass

In what ways would adding the nabh4 too early would interfere with your reaction?
Answers
NaBH4 is blind + will reduce other functional groups.
Functional groups:
The aldehyde group in o-vanillin would be converted to alcohol if it had been added during step one (imine production). Because the carbon is not sufficiently nucleophilic, p-toluidine would not attack and imine would not form in the maximum yield.
Regardless of the other atoms in the molecule, a functional group is a collection of atoms that have specific chemical characteristics. Covalent bonds bind the atoms in a functional group to the other molecules in the molecule as well as to one another. Examples: Alcohol, Aldehyde, Ketone, Carboxylic acid, Halogens, Double & Triple covalent bonds.
A carbonyl in which the carbon atom is linked to at least one hydrogen atom is called an aldehyde. An R-group or a hydrogen atom could be the other group joined to the carbonyl. Aldehydes are a highly reactive form of carbonyl because of the tiny size of the hydrogen atom, which makes it relatively simple for other molecules to approach the partial positive charge on the carbonyl carbon. Aldehydes are adaptable reactants used in numerous different organic synthesis processes. Numerous aldehydes also have unique tastes and odors.

Write the balanced equation for the reaction of 1 mol of naoh with 1 mol of h2po4
Answers
Answer:
3 NaOH + H₃PO₄ -----> Na₃PO₄ + 3 H₂O
Explanation:
This appears to be a double-displacement reaction. In these reactions, the cation of one compound is swapped with the cation of another. Therefore, Na⁺ (from NaOH) is swapped with H⁺ (from H₃PO₄). When constructing the new compounds, you may need to alter the amount of each ion within a particular compound to to make it neutral.
New Product #1: Na₃PO₄
----------> Na⁺ and PO₄³⁻
----------> +1 + 1 + 1 + (-3) = 0
New Product #2: H₂O (or HOH)
----------> H⁺ and OH⁻
----------> +1 + (-1) = 0
Now that you know the products, you need to balance the chemical equation. An equation is balanced when there is an equal amount of each element on both sides. These amounts can be modified by adding coefficients.
The unbalanced equation:
NaOH + H₃PO₄ -----> Na₃PO₄ + H₂O
Reactants: 1 sodium, 5 oxygen, 4 hydrogen, 1 phosphorus
Products: 3 sodium, 5 oxygen, 2 hydrogen, 1 phosphorus
The balanced equation:
3 NaOH + H₃PO₄ -----> Na₃PO₄ + 3 H₂O

Answers
0.3147 concentration (in moles/l) of a saline (NaCl) solution will provide an isotonic eyedrop solution.
Isotonic eye drops
Because it might result in eye discomfort or tissue damage if it is not maintained, isotonicity is regarded as a crucial component of ophthalmic medicines. A few drops of blood are mixed with the test preparation before being examined and judged under a microscope at a magnification of 40. Isotonic solutions are those that have the same amount of water and other solutes in them as the cytoplasm of a cell. Since there is no net gain or loss of water, placing cells in an isotonic solution will not cause them to either shrink or swell.
We can calculate the osmotic pressure exerted by a solution using the following expression.
π = M . R . T
where,
π is the osmotic pressure
M is the molar concentration of the solution
R is the ideal gas constant
T is the absolute temperature
The absolute temperature is 37 + 273 = 310 K
