The density of the solid is 6.724 g/ml.
Density is the number of factors which can be people, animals, vegetation, or objects in a sure place. To calculate density, you divide the number of objects by the dimension of the place. The populace density of a rustic is the wide variety of human beings in that us of a divided by means of the location in square kilometers or miles.
The density of an amount to being counted is its mass divided by means of its quantity. it also includes measured at zero °C and at 1 atmosphere of stress. Density is vital in figuring out the buoyancy of materials in fluids, as well as in evaluating materials and other measurements.
The density of an object is certainly one of its maximum crucial and easily-measured physical properties. Densities are extensively used to perceive natural substances and to represent and estimate the composition of many varieties of combos.
density = mass/ volume
= 975g/145ml
= 6.724 g/ml

<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We do as follows:
0.24 g (1 mol / 342.3 g) (
6.022 x 10^23 molecules / 1 mol ) =4.222 x 10^20 molecules
</span>
The answer is C. because <span>particles settle out over time ,can block light and scatter light .</span>
He, ne , Ar - Noble gas elements have the highest ionization energy,
while francium (87) has the lowest ionization energy because it is so far from helium, in short atom near to helium has higher ionization energy and the atom who is far away from helium have low ionization energy.
