Answer 1

◇Given :-

Density of Mercury= 13.6 gcm^-3

Volume = 25 cm^3

◇ To find :-

The mass of Mercury

As , We know that

Density is defined as the mass per unit volume

★ Density= Mass / Volume

→ Mass = Density× Volume

• Let the Mass be m

→ m = 13.6×25

→ m = 340 g

● Mass of mercury = 340 gram

Answer 2

Explanation :

It's given that density of mercury is 13.6 g cm-³ . Volume of mercury is 25 cm³

What is the mass of mercury?

Mass is given by,

Mass = Density × Volume

Here,

• Density = 13.6 g cm-³
• Volume = 25 cm³

Substituting values,

⇒ Mass = 13.6 gcm-³ × 25 cm³

Here, cm-³ & cm³ will get cancelled. Remaining is gram(g)

⇒ Mass = 13.6 g × 25

⇒ Mass = 340 g

∴ Mass of mercury = 340 grams.
