How much of a 2.0 M NaCl solution is needed to make 205.0 mL of 0.15 M NaCl solution?
svetlana [45]

Answer:

<h3>Step 1: </h3>

To relate the volume and molarity of a solution at two different concentrations, the expression used is :

M₁V₁ = M₂V₂

<h3>step 2:</h3>

(2M) V₁ = (0.15M)(250ML)

V₁ = 18.75

The 235U isotope (atomic mass = 235.00) undergoes fission when bombarded with neutrons. However, its natural abundance is only 0
Marianna [84]

Answer:

So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆

Explanation:

The rate of effusion of two gases A and B can be expressed by <em>Graham's law</em>:

\frac{EffusionRateA}{EffusionRateB}=\sqrt{\frac{M_{B}}{M_{A}} }

Where M is the molar mass, and in this case A is ²³⁵UF₆ while B is ²³⁸UF₆.

So now we <u>calculate the molar mass of each mass</u>:

²³⁵UF₆ ⇒235 + 6*19 = 349 g/mol

²³⁸UF₆ ⇒238 + 6*19 = 352 g/mol

Putting the data in Graham's law:

\frac{Rate^{235}UF_{6}}{Rate^{238}UF_{6}}=\sqrt{\frac{352}{349} } = 1.0043

So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆.
