This type of compound represents ionic because there is a metal and a non-metal elements
Answer:
<h2>The answer is 334 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of ethanol = 423 cm³
density = 0.789 g/cm³
So we have
mass = 0.789 × 423 = 333.747
We have the final answer as
<h3>334 g</h3>
Hope this helps you
In the blank there will be WAVELENGTH.
In a longitudinal wave, the WAVELENGTH is the distance from one compression to the next compression or from one rarefaction to the next rarefaction.
The chemical formula for helium is He. It is a noble gas with stable configuration 1s² and atomic number is 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomicgas that heads the noble gas group in the periodic table.
