Answer:
933.33 g/cm³
Explanation:
Density = mass / volume
Density = 2800/3 = 933.3 g/cm³.
Percent by mass : 4.10⁺³%
<h3>Further explanation</h3>
The concentration of a solution can be expressed in units such as molarity, normality, mass percent, volume percent etc.
mass solute= mass of NaOH
mass of NaOH :
mass solution = 1000 g
% mass :
By Boyles Law (P1V1=P2V2), substituting values in and solving for V2, we find that the new volume is 3.6 L<span />
This is known as the element IR. (<span>Iridium) Iridium has the atomic number of 77 therefore has </span>
"77 protons, 77 electrons, and 116 neutrons." You can figure out how many protons and electrons a element has by looking at the atomic number. In this case the atomic number is 77 therefore it will have 77 protons and electrons!
Hope this helps!
