Find the mass of the object (in grams) and find its volume by the volume of water it displaces (in cubic centimetres). Divide the mass by the volume to obtain the density (grams/cubic centimetre). This value can then be compared with known densities of the platinum, generally accepted as 21.45 g cm – 3 .
What is the density of platinum?
The atomic structure of these metals means they can bond easily with other elements. It is also one of the densest elements at 12.4 ounces per cubic inch ( 21.45 grams per cubic centimeter ), a little more than 21 times the density of water or 6 times the density of a diamond according to Chemicool.
What is the density of gold and platinum?
| Property Gold Platinum | Density (gram per cubic centimeter) 19.32 21.45 | Melting Point (°F) 1948.24 3222 | Boiling Point (°F) 5058 6921 | Density (punds per cubic inch) 0.697 0.883 |

Is platinum higher density?
So pure platinum is higher density than gold . The Mindat says gold density is 15 to 19.3 g/cc and platinum is 14 to 19 g/cc as found in nature. Pure platinum is well known to be 11 % higher density in pure form than pure gold. There may be confusion about density and specific gravity.
How do you find the known density?
The formula for density is the mass of an object divided by its volume. In equation form, that’s d = m/v , where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m3.
Is platinum heavy or light?
Platinum is a very strong and heavy metal . The wearer of a platinum piece will have to decide if they can handle a heavier metal like platinum over a lighter metal like white gold.
Is platinum better than gold?
While platinum is typically stronger and more durable, it is still a softer metal than gold making it more vulnerable to scratches. ... Whether you decide to choose a white gold or platinum ring, they are both precious metals, meaning your ring will look beautiful either way.
What is the price of platinum today?
| Platinum Spot Prices Today Change | Platinum Prices Per Ounce $982.00 -2.00 | Platinum Prices Per Gram $31.57 -0.06 | Platinum Prices Per Kilo $31,571.30 -64.30 |

What makes platinum valuable?
Platinum is a light gray metal between silver and nickel, and it’s harder than both silver and gold. Platinum is valuable because it’s rare and it’s used in many items . Nearly two thirds of the supply comes from South Africa, and Russia is the second-largest supplier. There are very few North American platinum mines.
Which has more density gold or platinum?
Strength. Platinum is roughly 60% more dense than gold . This is the reason why the same design in Platinum will be heavier than gold. Although gold can be considered stronger in the sense of it being harder to bend, the density of Platinum and its unlikelihood of wearing away from daily wear gives it the advantage.
What is the symbol of density?
The symbol for density is the Greek letter rho , What is the density of a material if 450 cm 3 of it has a mass of 200 g?
What is density measured in?
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm 3 ) . Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
What has the density of 1?
| Density Name # | 0.0899 g/L Hydrogen 1 | 0.1785 g/L Helium 2 | 0.9 g/L Neon 10 | 1.2506 g/L Nitrogen 7 |

Does platinum get dull?
The platinum band scraping against the same surface moves, and its scratch may look a bit deeper. This is because the metal is softer. ... Platinum becomes dull because of this . This dullness happens more swiftly than people like.
Why is platinum so cheap right now?
With mining stalled, the global platinum market entered a supply deficit. In other words, demand for platinum is exceeding the available supply of the precious metal. During the first quarter of 2021, demand for the metal rose by 26%.
Which is better white gold or platinum?
“ Platinum always tends to be more popular than white gold for engagement rings. It is a rarer metal and more durable,” Sachs reveals. ... There isn’t much of a difference in style between platinum and white gold. However, jewelers usually prefer to work with platinum since it is a more malleable metal.
