Calculate the number of atoms per cubic meter in aluminum. The density and atomic weight of aluminum are 2.70 g/cm3 and 26.98 g/

olya-2409 [2.1K]

Answer:

The number of Aluminium atoms present in per cubic meter is $N=6.02\times 10^{28}\ atoms/m^3$

Explanation:

Given the density of Aluminium $(\rho )$ is $2.70\ g/cm^3$

And the atomic weight of Aluminium $(A_{Al})$ is $26.98\ g/mol$

Also, the Avogadro's number $(N_A)$ is $6.023\times 10^{23}\ atoms/mol$

We need to find the number of atoms per cubic meter $(N)$

$N=\frac{\rho N_{A}}{A_{Al}}$

Plug the given values in the formula we get,

$N=\frac{2.70\times 6.022\times 10^{23}}{26.98}\\ \\N=0.602\times 10^{23}\ atoms/cm^3\\N=6.02\times 10^{22}\ atoms/cm^3\\N=6.02\times 10^{22}\times10^6\ atoms/m^3$

$N=6.02\times 10^{28}\ atoms/m^3$

So, the number of Aluminium atoms present in per cubic meter is $N=6.02\times 10^{28}$

If a chemical has a pH of 3, how could you alter its pH value to be more basic?

Andreyy89

Answer; If a chemical has a pH of 3, how could you change its pH value to be more basic? Adding water to a chemical will dilute the acid, thus lowering the pH value to more basic.
