What is the organic compound?

Answer:

1.0 M is the concentration of hydrochloric acid.

Explanation:

$HCl (aq) + NaOH (aq) \rightarrow H_2O (l) + NaCl (aq)$

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $HCl$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=1\\M_1=?\\V_1=50.0 mL\\n_2=1\\M_2=2.0 M\\V_2=25.0 mL$

Putting values in above equation, we get:

$1\times M_1\times 50.0 mL=1\times 2.0 M\times 25.0 mL$

$M_1=\frac{1\times 2.0 M\times 25 mL}{1\times 50.0 mL}=1.0M$

1.0 M is the concentration of hydrochloric acid.

Answer:

463.0 g.

Explanation:

<em>n = mass/molar mass.</em>

where, n is the mass of copper(ii) fluoride (m = 4.56 mol),

mass of copper(ii) fluoride = ??? g.

molar mass of copper(ii) fluoride = 101.543 g/mol.

∴ mass of copper(ii) fluoride = (n)(molar mass) = (4.56 mol)(101.543 g/mol) = 463.0 g.
