Calculate the molarity of a solution with 233.772g sodium chloride dissolved in 2,000mL of water

LekaFEV [45]

Answer:

The molarity is 2M

Explanation:

First , we calculate the weight of 1 mol of NaCl:

Weight 1mol NaCl= Weight Na + Weight Cl= 23 g+ 35, 5 g= 58, 5 g/mol

58,5 g---1 mol NaCl

233,772 g--------x= (233,772 g x1 mol NaCl)/58,5 g= 4 mol NaCl

<em>A solution molar--> moles of solute in 1 L of solution:</em>

2 L-----4 mol NaCl

1L----x0( 1L x4mol NaCl)/4L =2moles NaCl---> 2 M

bekas [8.4K]

Answer:

$3.4\times 10^3 eggs$ are produces are in a month.

Explanation:

Quantity of eggs produced by the chicken in a month = 284 dozens

1 dozen = 12 eggs

Number of eggs in a month:

$284 dozens = 284\times 12 eggs =3,408 eggs\approx 3.4\times 10^3 eegs$

$3.4\times 10^3 eggs$ are produces are in a month.

12. In a gas mixture consisting of carbon dioxide (CO2) and nitrogen (N2), the carbon dioxide molecules have a root-mean-square

zaharov [31]

Answer:

The correct answer is option e.

Explanation:

The formula used for root mean square speed is:

$\nu_{rms}=\sqrt{\frac{3kN_AT}{M}}$

where,

$\nu_{rms}$ = root mean square speed

k = Boltzmann’s constant = $1.38\times 10^{-23}J/K$

T = temperature

M = Molar mass

$N_A$ = Avogadro’s number = $6.02\times 10^{23}mol^{-1}$

Root mean square speed of carbon dioxide molecule:

$\nu_{rms}= 550 m/s$

Temperature of the mixture = T =?

Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol

$\nu_{rms}=550 m/s=\sqrt{\frac{3\times 1.38\times 10^{-23}J/K\times 6.022\times 10^{23}mol^{-1}T}{0.044 kg/mol}}$

T = 533.87 K

Root mean square speed of nitrogen molecule:

$\nu'_{rms}= ?s$

Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol

$\nu'_{rms}=\sqrt{\frac{3\times 1.38\times 10^{-23}J/K\times 6.022\times 10^{23}mol^{-1}\times 533.87 K}{0.028 kg/mol}}$

$\nu'_{rms}=689.46 m/s\approx 689 m/s$

689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
