# What is fractional density?

## What is fractional density?

A packing density or packing fraction of a packing in some space is the fraction of the space filled by the figures making up the packing. In packing problems, the objective is usually to obtain a packing of the greatest possible density.

### How do you calculate density ratio?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

What is the density of ice?

0.9187 gram per cubic centimeter
Ice is less dense than liquid water which is why your ice cubes float in your glass. At the same temperature of 0°C, the density (mass per volume) of ice is 0.9187 gram per cubic centimeter (g cm-3 or g/cm 3) while that of liquid water is 0.9998 g cm-3 (Cohen et al. 2003).

What are the units of density?

Kilogram per cubic meter
Density/SI units

## How to convert a ratio to a fraction?

Convert ratios to fractions. The ratio to fraction calculator finds fraction equivalents of ratio terms and reduces the fractions to simplest form. Enter part-to-part or part-to-whole ratios. Say you have a bowl of fruit with 6 apples and 8 bananas. There are 14 total pieces of fruit and the ratio of apples to bananas is 6 : 8.

### Which is the numerator in the ratio to fraction?

The left side of the ratio is the numerator, and the right side is the denominator. The fraction can optionally be reduced after converting if needed. For example, let’s convert 3:2 to a fraction. A part-to-part ratio is an expression of the relationship between two subsets of a set.

How is the density of a grain calculated?

Grain density was calculated by subtracting the pore space volume from the total sample volume and then dividing the difference by the dry mass.

How is the dry density of a rock measured?

Dry density is measured on rocks without any water or fluid in their pores. See Figure 2 for dry density distribution of dolomite, shale, and sandstone. Figure 3. Distribution of wet density for dolomite, shale, and sandstone. Wet density is measured on fully saturated cores.
