Answer:

- V_{marmol}=39cm^3

- \rho=2.5\frac{g}{cm^3}

Explanation:

Hola,

En este caso, dado que el volumen del agua es 50 centímetros cúbicos y el volumen de la probeta con el bloque de mármol es 89 centímetros cúbicos, el volumen del mármol es:

V_{marmol}=89cm^3-50cm^3\\\\V_{marmol}=39cm^3

Ahora, la densidad la calculamos con la masa de mármol dividido por el volumen del mismo:

\rho =\frac{m_{marmol}}{V_{marmol}} =\frac{98g}{39cm^3} \\\\\rho=2.5\frac{g}{cm^3}

¡Saludos!

yuradex [85]

The atom positions in a general molecule of formula (not shape class) AXn that has shape square pyramidal at the corers of square and one at the above center of the square.

<h3>What is square pyramidal?</h3>

The square pyramidal is a shape geometry of the hybridization in which it consists of one lone pair and 5 bond pairs of electrons that repel each other and due to which the geometry changes from octahedral to square pyramidal.

As atoms are located at the four corners of the planer and one atom at the above center of the planner which is repelled by 4 atoms present at the corner of the planer.

Therefore, the atom positions in a general molecule of formula (not shape class) AXn that has a shape square pyramidal at the corners of the square and one at the above center of the square.
