Question

पारा का 13.6 ग्राम/ क्यूबिक से, मी,होने पर 5 लीटर पारे का भार कितना किलोग्राम होगा​

Answer 1

Answer:

The density of mercury is 13.6 g / cubic cm.

To find,

The weight of 5 liters of mercury?

Solution,

Density is equal to mass per unit volume.

d=\dfrac{m}{V}d=

V

m

m is mass of mercury

So,

\begin{gathered}m=d\times V\\\\m=13.6\ g/cm^3\times 5\ L\end{gathered}

m=d×V

m=13.6 g/cm

3

×5 L

Since, 1 L = 1000 cm³

\begin{gathered}m=13.6\ g/cm^3\times 5000\ cm^3\\\\m=68000\ g\\\\or\\\\m=68\ kg\end{gathered}

m=13.6 g/cm

3

×5000 cm

3

m=68000 g

or

m=68 kg

So, the mass of mercury is 68 kg
