If the molar mass of calcium hydroxide (Ca(OH)2) is 74.1 g/mol, how many grams of calcium hydroxide are required to prepare 2.00
Llana [10]

Answer:

88.92 grams of Ca(OH)₂ are required

Explanation:

Molarity means mol/L, so 0.6 M are the moles of solute in 1 L of solution.

In 2 L, we 'll have the double of moles, 1.2

Mol . molar mass = grams

1.2 mol . 74.1 g/m = 88.92 grams of solute

How do i balance the equation<br><br> CCl4 +SbF3-----&gt; CCl2F2 + SbCl3
zaharov [31]

Answer:

3CCl4 + 2SbF3 → 3CCl2F2 + 2SbCl3

Explanation:

<em>CCl4 +SbF3 → CCl2F2 + SbCl3</em>

<em />

On the left side we have 3 times F, on the right side we have 2 times F

To balance we have to multiply SbF3 (on the left side) by 2

On the right side, we have to multiply CCl2F2 by 3

<em>CCl4 +2SbF3 → 3CCl2F2 + SbCl3</em>

On the left side we have 2x Sb, on the right side we have 1x Sb

So we have to multiply, on the right side, SbCl3 by 2

<em>CCl4 +2SbF3 → 3CCl2F2 + 2SbCl3</em>

On the right side, we have 12 times Cl, on the left side we have 4 times Cl

We have to multiply, on the left side, CCl4 by 3. The balanced equation is:

<em>3CCl4 + 2SbF3 → 3CCl2F2 + 2SbCl3 </em>
