or is the conversion factor used to convert mole to particle.
<u>Explanation:</u>
The Avogadro's number named after the scientist "Amedeo Avogadrothe" and represented as <em>N</em> or <em>N </em>0. It is the number of constituent particles like atoms, molecules or ions which are present in one mole of salt or compound.
It is the dimensionless and international unit of amount of substance given as . The number of particles like atoms, molecules or formula units can be converted to moles by dividing the given particle value by Avogadro's number. . For example, if u want to convert molecules of into moles, then have to do as below,
The value of the Avogadro constant has been selected for all experimental purpose so that the mass of 1 mole of a chemical compound (in grams) is numerically equal to the average mass of one molecule of the compound.
we need the three measurements to be able to asses significant figures.
Because there are many numbers of the human measurement . we must manage the uncertainly doing calculations because we can know what we are calculating.
A binary ionic compound is composed of ions of two different elements. One of which is a metal, and the other a non-metal
Answer:
The answer to your question is: letter B
Explanation:
First, write the reactions and balance them
a. 2 CH3OH + 3 O2 ⇒ 2 CO2 + 4 H2O
ratio 3/2 = 1.5
b. 2 CH2 = CHCH3 + 9 O2 ⇒ 3 CO2 + 3 H2O
ratio 9/2 = 4.5
c. 2 CH ≡ CH + 5 O2 ⇒ 4 CO2 + 2 H2O
ratio 5/2 = 2.5
