The mass in grams is 487.5 for methanol.
We must calcuate the grams of a compound through the molar mass of it.
Molar mass of methanol: 32.04 g/mol
We know that 1 mol has NA molecules and they weigh 32.04 g so, this is the rule of three we must make:
6.02x10²³ molecules _____ 32.04 g
9.16x10²⁴ molecules _____ (9.16x10²⁴ . 32.04) / 6.02x10²³ = 487.5 g
How many valence electrons does dichromate ion have?
Which spectrum of hydrogen consists of the Lyman, Balmer, and Paschen series?
There are two types of spectrum: Line and continuous.
In line spectrum we observe emission or absorption line at some particular wavelength range.
In case of hydrogen spectrum, initially, there were following lines observed in the emission spectrum of hydrogen:
So all these are the part of line spectrum of hydrogen.
When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is ________ the concentration of the ketone?
Much lower than ketone is more stable than enol. N, 4-Dimethylpent -4-en-2-Amine (NH_3 protonated in acidic protoned in acidic conditions) d. [Proton cannot re extracted from OH in acidic conditions to firm O^(-)].
What do the coefficients in front of the reactants and products in a chemical reaction represent ?
Coefficients are used in all chemical equations to show the relative amounts of each substance present. This amount can represent either the relative number of molecules, or the relative number of moles (described below). If no coefficient is shown, a one (1) is assumed.
