Question

Find the mass of 555 cm³ of iron in kg when density of iron is 7.6 g/cm³​

Answer 1

Answer:

Mass of iron:-4.218kg

Explanation:

Density = Mass/Volume

ρ = M/V

Hence,

Mass = Density * Volume

M = ρV

Given that,

Density = ρ = 7.6 g/cm³

Volume = V = 555cm³

Therefore, putting all the values in we get,

Mass = Density * Volume

M = ρV

M = 7.6 * 555

M = 4218 g

M = 4.218 kg

Answer 2

Answer

• Mass of Iron = 4.218 kg

Given

• Volume of iron is 555 cm³ and density of iron is 7.6 g/cm³

To Find

• Mass in kg

Formula Used

• Density

• It is defined as mass per unit volume

$\bigstar \bf \;\; Density=\dfrac{Mass}{Volume}$

Solution

Volume , V = 555 cm³

Density , D = 7.6 g/cm³

Mass , m = ? kg

Apply formula .

$\implies \rm Density=\dfrac{Mass}{Volume}\\\\\implies \rm D=\dfrac{m}{V}\\\\\implies \rm 7.6=\dfrac{m}{555}\\\\\implies \rm m=7.6 \times 555\\\\\implies \rm m=4218\ g\\\\\implies \rm m=4.218\ kg$

So , Mass of Iron is 4.218 kg's.
