4. A piece of iron when immersed in water taken in a Eureka can displaces 25 mL of water. Its mass is 195 g. Find the density of iron in kg m-?.

$\huge\orange{\overbrace{\red{\underbrace{\color{pink}{{\red\:{✎Solution}}}}}}}$

$\huge\orange{✧Given,}$

➢ Mass of iron piece M = 195 g =>0.195 kg

$\orange{✦Volume\:of\:iron\:piece,}$

$V \:⇒\:Volume\:of\:water\:displaced$

$⇒\:25 \: cm {}^{3} = 25 \times 10 {}^{ - 6} \: m {}^{3}$

$\orange{✧Density\:of\:iron,}$

$d⇒ \frac{M}{V} \\ \\ ⇒\frac{0.195 \: kg}{25 \times 10 { }^{ - 6}m {}^{3} } \\ \\ ⇒ \: 7800 \: kg \: m {}^{ - 3}$
