The density of a gold nugget is 19.3 g/cm3. If the volume of the gold nugget is 0.00369 L the mass of the nugget is
Sauron [17]

Answer:

The answer to your question is 71.22 g

Explanation:

Data

Density = 19.3 g/cm³

Volume = 0.00369

mass = ?

Formula

Density = \frac{mass}{volume}

Solve for mass

mass = density x volume

Process

1.- Convert volume from liters to cubic centimeters

                 1 l ----------------  1000 cm³

             0.00369l ---------   x

                x = (0.00369 x 1000 ) / 1

                x = 3.69 cm³

2.- Substitution

       mass = 19.3 x 3.69

3.- Simplification and result

       mass = 71.22 g

A solution has an H3O+ concentration of 3.5 x 10^-5 M. Is it acidic or basic?
irakobra [83]

The mass of NaCl produced is 0.117 g.

<h3>What is the pH?</h3>

The pH of a solution is what tells us if the solution is acidic or basic. The solution is acidic if the pH of the solution is less than 7.

1) pH = - log(3.5 x 10^-5 M)

= 4.45

Thus the solution is acidic.

2) We can see that the concentration as given is the concentration of OH^-

[OH ] = 4.0 x 10^-3 M

pOH = -log (4.0 x 10^-3 M)

pOH = 2.39

pH = 14 -  2.39

pH = 11.61

The equation of the reaction is; NaOH + HCl ----- > NaCl + H2O

Number of moles of NaOH =  0.40 M * 10/1000 = 0.004 moles

Number of moles of HCl = 0.20 M  * 10/1000 = 0.002 moles

We can see that HCl is the limiting reactant

Mass of NaCl produced ;

0.002 moles * 58.5 g/mol = 0.117 g

which equation is setup correctly to determine the volume of a 1.5 mol sample of oxygen gas at 22 degrees Celsius and 100 kPa
rjkz [21]
Hello!

We have the following data:


v (volume) = ? (in L)
n (number of mols) = 1,5 mol
T (temperature) = 22 ºC 
First let's convert the temperature on the Kelvin scale, let's see:
TK = TºC + 273,15
TK = 22 + 273,15
TK = 295,15

P (pressure) = 100 kPa → P = 100000 Pa → P ≈ 0,987 atm
R (gas constant) = 0,082 atm.L / mol.K

<span>We apply the data above to the Clapeyron equation (gas equation), let's see:

</span>P*V = n*R*T

0,987*V = 1,5*0,082*295,15

0,987V = 36,30345

V =  \dfrac{36,30345}{0,987}

\boxed{\boxed{V \approx 36,78\:L}} \end{array}}\qquad\checkmark

I hope this helps. =)

What's the difference between series and parallel circuit in table form?​
schepotkina [342]
Hey :)

In a parallel circuit, a different amount of current flows through each parallel branch of the circuit.

In the series circuit, different voltage exists across each component in the circuit.

Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.


Hope this helps :)
