Answer: Molar mass of is 17.03 g
Explanation:
Molar mass is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
It is found by adding the atomic masses of all the elements present.
Atomic Mass of Nitrogen (N) = 14.007 g
Atomic Mass of Hydrogen (H) = 1.008 g
Molar mass of = 1(14.007)+3(1.008) g = 17.03 g
Answer:
1. Phosphoric Acid : Catalyst
2. Methyl Anthranilate : Reactive
3. Sodium Nitrite : Reactive
4. Diethyl Ether : Solvent and reactant
5. Nitrogen : Sub-product
Explanation:
The phosphoric acid is used as a catalyst for the reaction, the methyl anthranilate will react with the sodium nitrite to produce methyl salicylate, along with the diethyl ether and the nitrogen is a sub-product of the reaction.
Answer : The correct option is, (b) 0.087
Explanation :
The formula used for relative saturation is:
where,
= partial pressure of ethyl acetate
= vapor pressure of ethyl acetate
Given:
Relative saturation = 50 % = 0.5
Vapor pressure of ethyl acetate = 16 kPa
Now put all the given values in the above formula, we get:
Now we have to calculate the molar saturation.
The formula used for molar saturation is:
and,
P(vapor free) = Total pressure - Vapor pressure
P(vapor) = = 8 kPa
So,
P(vapor free) = 100 kPa - 8 kPa = 92 kPa
The molar saturation will be:
Therefore, the molar saturation is 0.087
