Molar mass of aluminum ( Al ) = 26.98 g/mol

n = m / M

n = 0.50 / 26.98

n = 0.01853 moles

hope this helps!

Answer: The number of moles of 0.50 g Aluminium is 0.0185 moles.

Explanation:

To calculate the number of moles, we use the formula:

$Moles=\frac{\text{Given mass}}{\text{Molar mass}}$

In the given question:

Given mass of Aluminium = 0.50 g

Molar mass of Aluminium = 27 g/mol

Putting values in above equation, we get:

$\text{Moles of Aluminium}=\frac{0.50g}{27g/mol}=0.0185moles$

Hence, the number of moles of 0.50 g of Aluminium is 0.0185 moles.

makvit [3.9K]

Answer:

The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.

The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.

8. The time period of artificial satellite in a circular orbit of radius R is T. The radius of the orbit in which time period is

Elena-2011 [213]

Explanation:

It is given that,

The time period of artificial satellite in a circular orbit of radius R is T. The relation between the time period and the radius is given by :

$T^2\propto R^3$

The radius of the orbit in which time period is 8T is R'. So, the relation is given by :

$(\dfrac{T}{T'})^2=(\dfrac{R}{R'})^3$

$(\dfrac{T}{8T})^2=(\dfrac{R}{R'})^3$

$\dfrac{1}{64}=(\dfrac{R}{R'})^3$

$R'=4\times R$

So, the radius of the orbit in which time period is 8T is 4R. Hence, this is the required solution.
