Volume = 0.50 L
Molar mass KBr = 119.002 g/mol
Molarity = 0.125 M
Mass ( KBr) = ?
mass = molarity * molar mass * volume
mass = 0.125 * 119.002 * 0.50
mass = 7.437625 g of KBr
hope this helps!
Answer:
8 mol
Explanation:
Step 1: Calculate the mass of PtCl₄ in the sample
10.00 grams of a sample of hydrated PtCl₄ are heated and lose 3.00 g of water. The mass of PtCl₄ is:
mPtCl₄ = 10.00 g - 3.00 g = 7.00 g
Step 2: Calculate the moles corresponding to 7.00 g of PtCl₄ and 3.00 g of H₂O
The molar mass of PtCl₄ is 336.9 g/mol.
7.00 g × 1 mol/336.9 g = 0.0208 mol
The molar mass of H₂O is 18.02 g/mol.
3.00 g × 1 mol/18.02 g = 0.166 mol
The molar ratio of H₂O to PtCl₄ is:
0.166 mol H₂O/0.0208 mol PtCl₄ ≈ 8 mol H₂O/ 1 mol PtCl₄
Explanation:
Reaction equation for this reaction is as follows.
It is given that 
= 0.0118.
According to the ICE table,
Initial: 0.86 0.86 0 0
Change: -x -x +x +x
Equilibrium: 0.86 - x 0.86 - x x x
Hence, value of will be calculated as follows.
0.0118 = 
x = 0.084 atm
Thus, we can conclude that 
is 0.084 atm.
<h3><u>Answer;</u></h3>
Atomic particles
The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.
<h3><u>Explanation</u>;</h3>
- Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
- <em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
- Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions
