Answer:
The molar mass of the acid is 1067.42 g/mol
Explanation:
A monotropic acid can donate one proton only in a acd base reaction thus
Monotropic acid + NaOH → NaSalt + H₂O
From the above reaction, one mole of NaOH reacts with one mole of monotropc acid
however there are 0.1578 M NaOH from 15.24 mL hence we have
Number of moles of NaOH = 0.1578 M/L × (15.24/1000) L = 0.002404872 M of NaOH
The number of moles of the monotropic acid = number of moles of NaOH = 0.0024 M. However Number of moles = mass/(molar mass)
Therefore molar mass = mass/number of moles = 2.567(2.4×10⁻³) = 1067.42 g/mol
Answer:
Explanation:
We cause air pollution directly through our use of electricity, fuels, and ... Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, ... Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned ... with ozone-forming nitrogen oxides and volatile organic compound emissions.
To calculate the number of molecules, we can simply use this rule:
number of molecules = number of moles x Avogadro's number
In this problem, we have:
number of moles = 4.56 moles
Avogadro's number is a constant = 6.02 x 10^23
Substituting in the above equation, we can calculate the number of molecules as follows:
number of molecules = 4.56 x 6.02 x 10^23
= 2.74512 x 10^24 molecules
Protons-33
neutrons-42
electrons-33
