A metal cube has a mass of 20 g and a volume of 5 ml. What is the density? Is the cube made of pure aluminum? Explain your answe
Shtirlitz [24]

Explanation:

Given that,

Mass of metal cube, m = 20 g

Volume of cube, V =5 mL

We need to find the density of the cube. Mass per unit volume equals density.

d=\dfrac{m}{V}\\\\d=\dfrac{20\ g}{5\ mL}\\\\d=4\ g/mL

So, the density of the cube is 4 g/ml.

We know that the density of Aluminium is 4 g/mL.

So, the cube is not Aluminium cube.

Natasha_Volkova [10]

Answer:

17.04%

Explanation:

Actual Value = 173.1

Measured Value = 143.6

Percent error is obtained using the equation;

Percent error = (Measured - Actual) / Actual ]* 100

Percent error = [ (143.6 - 173.1) / 173.1 ] * 100

The absolute value of (Measured - Actual) is taken,

Percent Error = [29.5 / 173.1 ] * 100

Percent Error = 0.1704 * 100 = 17.04%

Can somebody help me please? it’s urgent
Anettt [7]

Answers:

See attached table

Explanation:

The isotope symbol will have the mass number and chemical symbol.  The atomic number will be equal to the number of protons because the atomic number is the number of protons in an atom.  The electrons will be equal to the protons because the atom is neutral.  The neutrons can be found by subtracting the number of protons from the mass number.  The mass number can be found by adding the protons and neutrons.  It is also in the name of the isotope.
