The molar mass of the gas is 35. glmol.
the molar mass of a chemical compound is described as the mass of a sample of that compound separated by the amount of substance in that sample, measured in moles.
The molar mass is a bulk, not molecular, effects of a substance.
<h3>What is molar mass and how is it calculated?</h3>
The molar mass is the mass of one mole of a sampling. To find the molar mass, count the atomic masses (atomic weights) of all of the atoms in the molecule. Find the atomic mass for each element by using the mass shown in the Periodic Table or table of atomic weights.
<h3>What is molar ?</h3>
Molar refers to the unit of concentration molarity, which is equivalent to the number of moles per liter of a solution. In chemistry, the word most often guides to molar concentration of a solute in a solution. Molar attention has the units mol/L or M.

From start:
Joule, J, calorie,
Example 1: 120 J / 4.184 = 28.68 cal
Example 2: 1200 cal * 4.184 = 5020.8 J
Blue litmus paper turns red in the presence of an acid. Therefore, it can be assumed that the substance in the beaker is an acid.
Acids have a pH level of less than 7. Consequently, it can be assumed that the substance has a pH level less than 7.
Answer:
FeSO₄ is the Limiting Reactant
Explanation:
3FeSO₄(aq) + 2(NH₄)₃PO₄ (aq) => 3(NH₄)₃PO₄(aq) + Fe₃(PO₄)(s)
315ml(1.25M)FeSO₄ + 405ml(0.95M)(NH₄)₃PO₄
=> 0.315L(1.25M)FeSO₄ + 0.405ml(0.95M)(NH₄)PO₄
=> 0.394mole FeSO₄ + 0.385mole (NH₄)PO₄
Divide by respective coefficient => the smaller value is the Limiting Reactant.
=> 0.394/3 = 0.131 => 0.385/2 = 0.193
Smaller value is associated with FeSO₄
∴the limiting reactant is FeSO₄.
Summery:
1. convert reactant quantities to moles
2. divide reactants by respective coefficients of balanced equation
3. note smaller value after dividing by respective coefficient => Limiting Reactant.
As the name hypochlorous acid suggest that it is acidic, no matter what is the concentration of the acid, the acid solution is acidic as it provides hydronium or hydrogen ions to the aqueous solution.
HClO (aq) ↔ H⁺ (aq) + ClO⁻ (aq)
Hypochlorous acid or HClO is a weak acid, while NaOH is a strong base. The formation of NaOCl takes place when these two react. NaOCl is a salt of a strong base and a weak acid, and due to this, the solution of sodium hypochlorite is basic.
Sodium is the spectator ion, that is, it does not need to be represented at the time of demonstrating the net equation for the hydrolysis of sodium hypochlorite.
ClO⁻ (aq) + H2O (l) ↔ HOCl (aq) + OH⁻ (aq)
On observing the first equation, on the product side, there are hydrogen ions, which signifies that the solution is acidic, and if we observe at the second equation, on the product side hydroxide ion is witnessed that indicates that the solution is basic.
