The mass of copper metal is 6.342 g and ...

The mass of copper metal is `6.342 g` and the density of copper is `7.6 g//cm^(3)`. What is its volume ?

Text Solution

Verified by Experts

Mass of copper metal `= 6.342 g`
Density of copper metal `= 7.6 g//cm^(3)`
Volume `= ("Mass")/("Density")=((6.342g))/((7.6g//cm^(3)))=0.834 cm^(3)`
The final result has to be reported upto two significant figures because the least pecise number (7.6) has two significant figures
`:.` In the final result, the digit 4 is dropped and the correct answer `=0.83 cm^(3)`
