Question

28 g of iron shot is added to a graduated cylinder containing 40cm of water. The water level rises to the 44cm mark. From this information, calculate the density of iron.

Answer 1

`\huge\fbox{Answer ☘}`

Volume of water displaced = Volume of shape

`\bold{⇢ ( \:44 \:- \:40\: ) \:mL}\\\bold{⇢ 4 \:mL}`

Weight = 28 g

`\bold\blue{density = (mass)/(volume)} \\ \\ \pink{ ⇢ \cancel (28)/(4) }\\ \\ \pink{⇢ 7 \: g \: ml {}^( - 1)}`
