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!

Mariana [72]

Answer:

The balanced molecular equation  for the reaction :

Cu(NO_3)_2(aq)+K_2CO_3(aq)\rightarrow CuCO_3(s)+2KNO_3(aq)

Explanation:

The reaction between copper(II) nitrate  and potassium carbonate gives solid precipitate of copper(II) carbonate and aqueous solution of potassium nitrate.

Cu(NO_3)_2(aq)+K_2CO_3(aq)\rightarrow CuCO_3(s)+2KNO_3(aq)

According to reaction, 1 mole of copper(II) nitrate reacts with 1 mole of potassium carbonate to give 1 mole of copper(II) carbonate and 2 moles of potassium nitrate,
