Question

Henry divides 1.060 g by 1.0 mL to find the density of his water sample. How many significant figures should he include in the

Answer 1

Answer:

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Mass = 1.060 g

Volume = 1.0 mL

Density in correct number of significant figures=  ?

Solution:

d = m/v

d = 1.060 g /  1.0 mL

d = 1.06 g/ mL

The density 1.06 g/mL contain three significant figures Henry should report it 1.1 g/mL having the only one digit after decimal because in given values 1.060 and 1.0 the least number of significant figures after the decimal is 1 that's why the final result must have one significant figure after  decimal.
