Lead has a density of 11.3 g/mL. If you have 105 grams of lead,
1 answer:
Answer:
<h2>Volume = 9.29 mL</h2>Explanation:
Density of a substance can be found by using the formula
From the question
Density = 11.3 g/mL
mass = 105 g
Substitute the values into the above formula and solve for the volume
That's
Cross multiply
11.3v = 105
Divide both sides by 11.3
v = 9.29203
We have the final answer as
<h3>Volume = 9.29 mL</h3>Hope this helps you

k = -0.006.
T₀ = 15 °C
Explanation:
Hola.
En este caso, considerando la gráfica mostrada en el archivo adjunto, podemos evidenciar que los datos dados se comportan de manera lineal, por lo que basado en la ecuación, T=k*h+To, podemos calcular la pendiente que basicamente es igual a k, tomando dos puntos en la gráfica:
Además, el valor de la temperatura inicial se puede extraer de la tabla, dado que esta es cuando la altura es 0 m, es decir 15 °C.

Answer:
1) 0.18106 M is the molarity of the resulting solution.
2) 0.823 Molar is the molarity of the solution.
Explanation:
1) Volume of stock solution =
Concentration of stock solution =
Volume of stock solution after dilution =
Concentration of stock solution after dilution =
( dilution )
0.18106 M is the molarity of the resulting solution.
2)
Molarity of the solution is the moles of compound in 1 Liter solutions.
Mass of potassium permanganate = 13.0 g
Molar mass of potassium permangante = 158 g/mol
Volume of the solution = 100.00 mL = 0.100 L ( 1 mL=0.001 L)
0.823 Molar is the molarity of the solution.
