In a titration experiment, 31. 4 ml of 1. 120 M HCOOH is neutralized by 16. 3 ml of Ba(OH)_{2}. So, the concentration of the Ba(OH)_{2}  solution is 23.16 M

Calculation,

The formula for the dilution of a solution is given as:

M_{1} V_{1} = M_{2} V_{2}

Where M is molarity and V is the volume of the solution in liters ( L ).

Given data,

M_{1} =  120  M

V_{1} =31. 4 ml

M_{2} = ?

V_{2} = 16. 3 ml

120  M ×31. 4 ml  =  M_{2}  ×  16. 3 ml

M_{2}  = 120  M ×31. 4 ml / 16. 3 ml =23.16 M

In a titration experiment, the concentration of the Ba(OH)_{2}  solution is 23.16 M

A gas system has an initial number of moles of 0.693 moles with the volume unknown. When the number of moles changes to 0.928 mo
lara [203]

Answer:

The initial volume in mL is 5959.2 mL

Explanation:

As the number of moles of a gas increases, the volume also increases.  Hence, number of moles and volumes are directly proportional i.e

n ∝ V

Where n is the number of moles and V is the volume

Then, n = cV

c is the proportionality constant

∴n/V = c

Hence n₁/V₁ = n₂/V₂

Where n₁ is the initial number of moles

V₁ is the initial volume

n₂ is the final number of moles

and V₂ is the final volume.

From the question,

n₁ = 0.693 moles

V₁ = ?

n₂ = 0.928 moles

V₂ = 7.98 L

Putting the values into the equation

n₁/V₁ = n₂/V₂

0.693 / V₁ = 0.928 / 7.98

Cross multiply

∴ 0.928V₁ = 0.693 × 7.98  

0.928V₁ = 5.53014

V₁ = 5.53014/0.928

V₁ = 5.9592 L

To convert to mL, multiply by 1000

∴ V₁ = 5.9592 × 1000 mL

V₁ = 5959.2 mL

Hence, the initial volume in mL is 5959.2 mL

How many moles of NaCl are needed to make 10.0L of a 5 M solution of<br> Salt water?*
vesna_86 [32]

Answer: 50 mol

Explanation:

Molarity=\frac{Moles -of -solute}{liters -of -solution}

M=\frac{mol}{L}

mol=M*L

mol=5*10\\mol=50mol
