Correct Answer – C
Here, mass, `m=4.237g`
Volume, `V=2.5cm^(3)`
Density `rho=(“mass”)/(“Volume”)=(4.237g)/(2.5cm^(3))=1.6948cm^(-3)`
As mass has 4 significant figures and volume has 2 significant figures, therefore, as per rule, density will have only two significant figures. Rounding off to two significant figures, we get `rho=1.7g” “cm^(-3)`
Correct Answer – C
In this question, density should be reported to two signigcant figures Density `= (4.237g)/(2.5cm^(3)) = 1.6948`
As rounding off the numbers, we get density `= 1.7`
