(1 point) How many mL of water is added to dilute a 10 mL of 0.4 M solution to a new concentration of 0.1 M?
LiRa [457]

Answer:

The volume of water added is 30 mL

Explanation:

Given data

  • Initial concentration (C₁): 0.4 M
  • Initial volume (V₁): 10 mL
  • Final concentration (C₂): 0.1 M
  • Final volume (V₂): ?

We can find V₂ using the dilution rule.

C₁ × V₁ = C₂ × V₂

0.4 M × 10 mL = 0.1 M × V₂

V₂ = 40 mL

The volume of water added is

V₂ - V₁ = 40 mL - 10 mL = 30 mL

Determine the empirical and molecular formula for chrysotile asbestos. Chrysotile has the following percent composition: 28.03%
Mariulka [41]

The empirical and molecular formula : Mg₃Si₂H₂O₈ and Mg₆Si₄H₄O₁₆

<h3>Further explanation</h3>

Given

28.03% Mg, 21.60% Si, 1.16% H, and 49.21% O

Required

The empirical and molecular formula

Solution

Mol ratio : Mg : Si : H : O =

\tt \dfrac{28.03}{24}\div \dfrac{21.6}{28}\div \dfrac{1.16}{1}\div \dfrac{49.12}{16}\\\\1.17\div 0.771\div 1.16\div 3.07\\\\1.5\div 1\div 1.5\div 4\\\\3\div 2\div 2\div 8

So empirical formula :

\tt Mg_3Si_2H_2O_8

(Emprical formula)n=molecular formula

(Mg₃Si₂H₂O₈)n=520.8

(24.3+28.2+2.1+8.16)n=520.8

(258)n=520.8⇒n=2

The molecular formula : Mg₆Si₄H₄O₁₆
