Some metal chips with a total volume of 3.29 cm3 are placed on a piece of paper and weighed. The combined mass is found to be 18.43 g, and the paper itself weighs 1.2140 g. Calculate the density of the metal to the proper number of significant figures.

d = 5.23 g/cm³

Explanation:

Given data:

Volume of metal chips = 3.29 cm³

Mass of metal chips and paper = 18.43 g

Mass of paper = 1.2140 g

Density of metal = ?

Solution:

Mass of metal = combined mass - mass of paper

Mass of metal = 18.43 g - 1.2140 g

mass of metal = 17.22 g

Density:

d = mass/ volume

d = 17.22 g/ 3.29 cm³

d = 5.23 g/cm³

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
