Answer:

M_2=0.613M_1

Explanation:

M_1 = Concentration of stock solution

M_2 = Concentration of solution

V_1 = Volume of stock solution = 19 mL

V_2 = Volume of solution = 0.31 L= 310 mL

We have the relation

M_1V_1=M_2V_2\\\Rightarrow M_2=\dfrac{M_1V_1}{V_2}\\\Rightarrow M_2=\dfrac{M_119}{310}\\\Rightarrow M_2=M_1\times\dfrac{19}{310}\\\Rightarrow M_2=0.613M_1

\boldsymbol{\therefore M_2=0.613M_1}

The concentration of the diluted solution will be 0.613 times the concentration of the stock solution.

A crime lab received a 235-gram sample. The sample had a molecular mass of 128.1 grams and the empirical formula is CH2O. How ma
kvv77 [185]

Explanation:

Given parameters:

Mass of sample = 235g

Molecular mass of sample = 128.1g

Empirical formula = CH₂O

Unknown:

Mass of each element in the sample = ?

Solution:

To solve this problem, we must know that the empirical formula of any compound is the simplest ratio of the atoms it contains. This is not the true formula of the compound.

      Molecular formula = (Empirical formula)ₙ

Let us find the molecular mass of the sample;

      CH₂O = 12 + 2(1) + 16 = 30g

   

      128.1  = (30)n

          n = 4

The molecular formula of the compound is;    (CH₂O)₄  = C₄H₈O₄

Now to find the grams of each element in the sample;

Express the molecular mass of each element and that of the compound as a fraction and multiply with the given mass;

    For C;

              \frac{4 x 12}{128.1}   x   235\\  = 88.06g

          H; \frac{8 x 1}{128.1}  x  235  = 14.68g

          O: \frac{4 x 16}{128.1} x 235 = 117.41g

serg [7]
The correct answer is letter (d.) Mg, Ca, Sr, Ba

These four elements are found in Group 2 of the periodic table, which are alkaline metals, therefore they have the very similar properties because of their 2 valence electrons, which makes them reactive.
