What is the mass, in grams, of a sample of 6.98 × 1024 atoms of magnesium (Mg)? Show your work or explain the steps that you use

CaHeK987 [17]

Hello!

* First Step: to know Avogrado's Law

We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:

** Second Step: to know the molar mass of the solute

The molar mass of of magnesium = 24.30 g/mol

*** Third step: make the ratio mass / mol with atoms

1 mol we have 6.02*10²³ atoms

1 mole of Mg we have 24.30 g

Then we have:

24.30 g ------------- 6.02*10²³ atoms

x ----------------------- 6.98*10^24 atoms

$\dfrac{24.30}{x} = \dfrac{6.02*10^{23}}{6.98*10^{24}}$

multiply cross

$6.02*10^{23}*x = 24.30*6.98*10^{24}$

$6.02*10^{23}\:x = 1.69614*10^{26}$

$x = \dfrac{1.69614*10^{26}}{6.02*10^{23}}$

$\boxed{\boxed{x \approx 281.75\:grams}}\end{array}}\qquad\checkmark$

I Hope this helps, greetings ... DexteR! =)

What are the values for % Cl and % F, respectively, for Sample II?

horsena [70]

Answer:

Explanation:

The mass percentages of chlorine and fluorine:

Given:

Mass of chlorine = 5.753g

Mass of fluorine = 9.248g

Find the total of the masses given:

Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g

% of Cl = $\frac{mass of chlorine}{total mass}$ x 100

% of Cl = $\frac{5.753}{15.001}$ x 100 = 38.35%

% of F = $\frac{mass of fluorine}{total mass}$ x 100

% of F = $\frac{9.248}{15.001}$ x 100 = 61.65%
