Question

Find the mass of silver having volume 400cm*3 and density 5g/cm*3.​

Answer 1

Mass = 2000g.

Given :-

• Volume (v) = 400cm³
• Density (d) = 5g/cm³ .

To Find :-

• Mass (m) = ?

Solution :-

As we know that,

$\dag \red {\boxed{ \tt{ \underline{ \: Density(d) = \: \frac{Mass(m)}{Volume(v)} }}}}$

[ Put the values ]

$\implies \: \rm \: 5 \frac{g}{ \cancel{cm {}^{3}} } = \frac{Mass}{400 \cancel{cm {}^{3} }}$

$\implies \rm \: 5 \times 400g\: = Mass$

$\implies \: \rm 2000g \: = Mass$

Thus, the mass of silver is 2000g.

Answer 2

Given :-

• Volume of silver = 400cm³
• Density of silver = 5g/cm³

To find :-

• Mass of silver

Solution :-

→ Density = Mass/volume

→ 5 = Mass/400

→ Mass = 400 × 5

→ Mass = 2000g

1kg = 1000g

Hence,

• Mass of silver is 2kg

Additional Information

• S.I unit of mass is kg
• S.I unit of volume is m³
• S.I unit of density is kg/m³
• The ratio of the mass of an object to it's volume is known as Density
