Answer:
Empirical formula is C₃H₃O.
Explanation:
Given data:
Mass of compound = 0.519 g
Mass of CO₂ = 1.24 g
Mass of H₂O = 0.255 g
Empirical formula = ?
Solution:
%age of C,H,O
C = 1.24 g/0.519 × 12/44 ×100 = 65.5%
H = 0.255 g/0.519 × 2.016/18 ×100 = 5.6%
O = 100 - (65.5+5.6)
O = 28.9%
Number of gram atoms of H = 5.6 / 1.01 = 5.5
Number of gram atoms of O = 28.9 / 16 = 1.81
Number of gram atoms of C = 65.5 / 12 = 5.5
Atomic ratio:
C : H : O
5.5/1.81 : 5.5/1.81 : 1.81/1.81
3 : 3 : 1
C : H : O = 3 : 3 : 1
Empirical formula is C₃H₃O.
Answer:
340 N
Explanation:
<u>Force formula</u>
The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
<u>Equilibrium</u>
It is a state of rest or balance due to the equal action of opposing forces. equal balance between any powers, influences, etc.; equality of effect. mental or emotional balance; equanimity: The pressures of the situation caused her to lose her equilibrium.<u>
</u>
Elemental analysis of a compound containing carbon, hydrogen, nitrogen, and oxygen gave the following mass percentages for each element: C: 42.36% H: 3.555% N: 16.47% O: 37.62% The <em>molar mass</em> of the compound is Molecular formula = C6H14N2O2 Consider the total mass of the compound =100g Then mass of carbon = 49.30 g Mass of hydrogen = 9.653 g Mass of nitrogen = 19.16 g Mass of oxygen = 21.89 g Molar mass of carbon = 12.0 g/mol
<h3>What is
molar mass ?</h3>
In chemistry, the molar mass of a chemical compound is determined by dividing its mass by the molecular weight of the component that makes up the sample. The molar mass of a substance is a bulk attribute rather than a molecular one. The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes. A terrestrial average and a function of the relative abundance of the isotopes of the constituent atoms on Earth, the molar mass is most frequently calculated using the standard atomic weights. For converting between a substance's mass and amount in bulk amounts, the molar mass is the proper unit.
