P - Parenthesis
E - Exponent
M - Multiplication (left to right)
D - Division (left to right)
A - Addition (left to right)

A piece of green jade has a mass of 23.401 g.if the sample of jade displaces 50.0 ml of water to 56.5 ml in a 100 ml graduated c
OleMash [197]

we know that

The density is equal to the formula

Density=\frac{mass}{volume}

in this problem we have

mass=23.401\ gr

<u>Find the volume of a piece of green jade</u>

Volume=56.5\ ml-50.0\ ml=6.5\ ml

Substitute the values in the formula of density

Density=\frac{23.401}{6.5}

Density=3.60\frac{gr}{ml}

therefore

<u>the answer is</u>

Density=3.60\frac{gr}{ml}
