<h3><u>Answer</u>;</h3>

= 226 Liters of oxygen

<h3><u>Explanation</u>;</h3>

We use the equation;

LiClO4 (s) → 2O2 (g) + LiCl, to get the moles of oxygen;

Moles of  LiClO4;

(500 g LiClO4) / (106.3916 g LiClO4/mol)

= 4.6996 moles

Moles of oxygen;

But, for every 1 mol LiClO4, two moles of O2 are produced;

= 9.3992 moles of Oxygen

V = nRT / P

= (9.3992 mol) x (8.3144621 L kPa/K mol) x (21 + 273) K / (101.5 kPa)

= 226 L of oxygen

Calculate the molar mass of cacl2
kirza4 [7]

Answer:

\boxed {\boxed {\sf 110.98 \ g/mol}}

Explanation:

The molar mass is the mass of a substance in grams per mole.

To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.

The compound given is:

CaCl_2

The compound has 1 Ca (calcium) and 2 Cl (chlorine).

 

Mass of Calcium

  • The molar mass of calcium is 40.08 g/mol
  • There is only one atom of Calcium in CaCl₂, so the number above is what we will use.

Mass of Chlorine

  • The molar mass of chlorine is 35.45 g/mol
  • There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2.
  • 35.45 * 2= 70.9 g/mol

Molar Mass of CaCl₂

  • Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine.
  • 40.08 g/mol + 70.9 g/mol =110.98 g/mol

The molar mass of CaCl₂ is <u>110.98 grams per mole. </u>
