<u>Answer:</u>

2400 mL

<u>Explanation:</u>

Ca + 2HCl \implies CaCl_2 + H_2

According to this equation, the stoichiometric ratio between Ca and HCl for the complete reaction is 1:2.

We know that the number of moles of Ca can be calculated using the mole formula. (<em>number of moles = mass / molar mass</em>)

Moles of Calcium = \frac{60}{40} = 1.5 mol

So the moles of HCl = 1.5 \times 2 = 3.0 mol

<em>Volume of HCl solution = Moles of HCl/ concentration of HCl</em>

Volume of HCl solution = \frac{3}{1.25} = 2400 mL

What is the density of a board dimensions are 5.54 cm x 10.6 cm X 199 cm and whose mass is 28.6kg
exis [7]

Answer:

d=2.44\ g/cm^3

Explanation:

Given that,

The dimensions of the board is 5.54 cm x 10.6 cm X 199 cm.

The mass of the board is 28.6 kg.

Since, 1 kg = 1000 grams

28.6 kg = 28.6 × 1000 g = 28600 grams

Density = mass/volume

So,

d=\dfrac{28600\ g}{(5.54\times 10.6\times 199)\ cm^3}\\\\d=2.44\ g/cm^3

So, the density of a board is 2.44\ g/cm^3.

A chemist prepares a solution of sodium carbonate by measuring out of sodium carbonate into a volumetric flask and filling the f
Vadim26 [7]

Answer:

The correct answer will be "9.45\times 10^{-5} \ mol/L".

Explanation:

We have:

Moles of solute (Na₂Co₃) = 18.9 \mu \ mol

                                           = 18.9\times 10^{-6}

                               1 \mu \ mol = 10^{-6} \ mol

Now,

The volume of the solution will be:

⇒  0.200 \ L

∴ {1 \ mL=0.001 \ L}

The formula to find the concentration will be:

⇒  Concentration = \frac{moles \ of \ solute \ (mol)}{Volume \ of \ solution \ (L)}

On substituting the given values, we get

⇒                          =\frac{18.9\times 10^{-6}}{0.200}

⇒                          =9.45\times 10^{-5} \ mol/L
