Can a gold nugget be pure if it is found to displace 19.3 ml of water and has a mass of 371 grams?

First of all you should look up the density value of pure gold which happens to be 19.3 grams per mL.
Then you compare this with the density value of this gold nugget and you'll find by calculation: 19.22 g/mL. (= 371 g/ 19.3 mL)
The nugget is gold. Trust me, It's the correct answer on online homework

An irregularly shaped gold nugget weighs 24.3g and is found to displace 1.26ml of water. Can it be determined if it is really gold?
You can make a fairly good guess. What the first part of the experiment is designed to do is find the volume of the irregularly shaped nugget. Archimedes is the first to be recorded as offering this solution to finding the volume of an irregularly shaped object. By submerging the object in water, the experimenter can determine the volume of water the object displaces. By knowing the weight of the nugget and the volume of the nugget, and by comparing that to the known density of gold, you can make a fairly good guess as to whether or not it is gold. Let's look. Your nugget displaced 1.26 ml of water. That's 1.26 cubic centimeters of water. The nugget weighs 24.3 grams. Your nugget weighs 24.3 grams per 1.26 cubic centimeters. Divide this out to find the weight per 1 cubic centimeter: 24.3 grams / 1.26 cc = 19.29 grams per cubic centimeter. The density of gold, its weight per unit of volume, can be looked up with ease. As the known density of your nugget is about 19.3 grams per cubic centimeter, which is the known density of gold, there is a strong case for your nugget to be gold.
A nugget of gold is placed in a graduated cylinder that contains 80 ml of water the water level rises to 225 ml after the nugget is added to the cylinder what is the volume of the gold nugget?
nugget is 175 ml
A nugget of gold is placed in a graduated cylinder that contains 85 mL of water The water level rises to 225 mL after the nugget is added to the cylinder What is the volume of the gold nugget?
145cm cubed
A nugget of gold is placed in a graduated cylinder that contains 80 mL of water the water level rises to 255 L after the nugget is added to the cylinder what is the volume of the gold nugget?
225-80=145, and 1mL=1cm3. So it's 145cm3.
What solid with a volume of 27cm3 will displace ml of water?
27ml

A nugget that is supposedly gold istested to determine its density It is found to displace 19.3ml of water and has a mass of 371 grams Is it gold?
Your "gold" nugget weighs 371 grams. It displaces 19.3 ml of water. The 19.3 ml of water is 19.3 cc of water. (Water weighs 1 gram per cubic cemtimeter.) You have a nugget that weighs 371 grams and has a volume of 19.3 cc. Let's see how much a cubic centimeter weighs by dividing the weight by the volume. 371 g / 19.3 cc = 19.2 g / 1 cc = 19.2 grams per cubic centimeter. As gold has a specific gravity of about 19.3, that means that it is 19.3 times as heavy as an equal volume of water. Water weighs 1g/cc and the nugget weighs 19.2g/cc, so it looks like the nugget may very well be gold. It certainly has about the right density. Remember that a gold nugget isn't pure gold. Its gold content can vary because there is always a bit of silver and/or copper as an alloy in the nugget. And the percent of gold will vary from the high 90's to the low 80's or even less, in some cases.
How many grams of water should a solid 1300 gram cube of iridium displace?
~58 If iridium has a density of 22.42 g/cm3, 1300 grams of iridium would displace 1300/22.42 grams of water (as water has a density of 1 g/cm3). The shape of the iridium is irrelevant.
How many ounces of a 64 ounces of water will 303 grams of platinum displace?
Platinum has a density of about 21.45 g/ml 303 grams will therefor displace 14.12 ml or roughly 1/2 ounce (british) of water
How many kilograms of water does a submerged 120 Cm cubed block displace?
If the water is pure and the atmospheric conditions are standard,then 120 cm of water has a mass of 120 grams.120 grams = 0.12 kg.
A supposedly gold nugget is tested to determine its densityIt is found to displace19.3 mL of water and has a mass of 371 g Could the nugget be made out of gold?
yes
Gold is a precious metal with a density of 19.3 grams per ml. If a piece of gold weighs 100 grams what volume in ml should this gold displace in water?
Volume = Mass / Density, so 100 grams of gold divided by 19.3 g/mL gives a volume of 5.18 mL or 5.18 cubic centimeters. 5.18 mL of gold will displace 5.18 mL of water.
