How many milliliters of 0.2560 M KCl solution will contain 20.00 g of KCl?

Chemistry
1 answer:
lutik1710 [3]3 years ago
3 0

Answer:

1048 mL

Explanation:

Step 1: Given data

  • Concentration of the solution: 0.2560 M
  • Mass of KCl (solute): 20.00 g

Step 2: Calculate the moles corresponding to 20.00 g of KCl

The molar mass of KCl is 74.55 g/mol.

20.00 g × 1 mol/74.55 g = 0.2683 mol

Step 3: Calculate the volume of the solution

Molarity is equal to moles of solute divided by liters of solution.

M = moles of solute / volume of solution

volume of solution = moles of solute / M

volume of solution = 0.2683 mol / (0.2560 mol/L)

volume of solution = 1.048 L = 1048 mL

Calculate the pH for each of the following cases in the titration of 50.0 mL of 0.210 M HClO(aq) with 0.210 M KOH(aq).
laiz [17]
<span>35.0 mL of 0.210 M
KOH molarity = moles/volume
 find moles of OH do the same thing for: 50.0 mL of 0.210 M HClO(aq) but for H+ they will cancel out: H+ + OH- -> H2O
 but you'll have some left over,
 pH=-log[H+] pOH
     =-log[OH-] pH+pOH

For the skeletal chemical equation BF3(g) + NaH(s) → B2H6(g) + NaF(s) what is the coefficient of B2H6 in the balanced equation?
KonstantinChe [14]

Answer:

Coefficient in front of the B_2H_6  in the balanced equation - 1

Explanation:

The unbalanced Chemical equation is shown below as:-

BF_3+NaH\rightarrow B_2H_6+NaF

On the left hand side,  

There are 1 boron atom and 3 fluorine atoms and 1 sodium and hydrogen atoms.

On the right hand side,  

There are 2 boron atoms and 6 hydrogen atoms and 1 sodium and fluorine atoms.

Thus,  

leftside, BF_3 must be multiplied by 2 to balance boron and right side, NaF must be multiplied by 6 to balance fluorine. Left side, NaH must be multiplied by 6 to balance sodium and hydrogen atoms.

Thus, the balanced reaction is:-

2BF_3+6NaH\rightarrow B_2H_6+6NaF

<u>Coefficient in front of the B_2H_6  in the balanced equation - 1</u>

Why is an alloy is often more useful than a pure metal
mrs_skeptik [129]
<h2>Answer:</h2>

A pure metal has specific properties. Sometimes we need that metal but with modified properties. So for the modification of properties we make alloys.

<h3>Explanation;</h3>
  • An alloy is a mixture of two elements, one of which is a metal.
  • Alloys often have properties that are different to the metals they contain.
  • This makes them more useful than the pure metals alone.
  • For example, alloys are often harder than the metal they contain.
