I'm pretty sure your answer should be CaCl2. Hope this helps! =^-^= (if I need to explain more just let me know.)
<h3><u>Answer;</u></h3>
= 5.1 g/L
<h3><u>
Explanation;</u></h3>
Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Number of moles is 1 since one mole has a mass equivalent to the molar mass.
Therefore; We can find the volume and thus get the density.
<em>V = nRT/P</em>
<em> = (1 × 0.08206 × 237)/3.510</em>
<em> = 5.5408 L</em>
<em>Hence; Density = mass/volume </em>
<em> = 28.26 g/5.5408 L</em>
<em> = 5.1 g/L</em>
<em>The Density is 5.1 g/L or 0.005 g/cm³</em>
You need to use Stoichiometry
