Answer:
1.32 moles.
Explanation:
From the question given above, the following data were obtained:
Density of Al = 2.70 g/cm³
Volume of Al = 13.2 cm³
Number of mole of Al =.?
Next, we shall determine the mass of Al.
This can be obtained as follow:
Density of Al = 2.70 g/cm³
Volume of Al = 13.2 cm³
Mass of Al =?
Density = mass / volume
2.7 = mass of Al / 13.2
Cross multiply
Mass of Al = 2.7 × 13.2
Mass of Al = 35.64 g
Finally, we shall determine the number of mole of Al. This can be obtained as follow:
Mass of Al = 35.64 g
Molar mass of Al = 27 g/mol
Number of mole of Al =?
Mole = mass / molar mass
Number of mole of Al = 35.64 / 27
Number of mole of Al = 1.32 moles
Thus, 1.32 moles of aluminum are present in the block of the metal.
Answer:
1.VOLUME– The amount of space an object takes up. Basic Unit (SI Unit) for Solids – Cubic Meter, m3. LENGTH/DISTANCE – The measurement between two points.
2.one particle per cubic meter.
3.it means it is heavier
4.In a liquid the particles are still close together but a little further apart than in a solid.
5.In gases the particles are much further apart than in solids or liquids.

Answer:
10.1 ms^-2
Explanation:
From;
v = u + at
v = final velocity
u = initial velocity
a= acceleration
t = time taken
To convert the velocity from Km/hr to m/s we us;
x * 1000/3600
Where x is the velocity in Km/hr
So;
799 * 1000/3600 = 221.9 m/s
11325 * 1000/3600 = 3145.8 m/s
4.8 minutes = 4.8 * 60 = 288 s
Applying the formula;
a= v - u/t
a = 3145.8 - 221.9/288
a = 10.1 ms^-2
