The density for a sample of a pure material with a volume of 5 cm3 and a mass of 20 grams is?
The idea is to divide the mass by the volume.
A cube has sides of 5 centimeters and a mass of 250 grams What is the density?
density = mass / volume density = 0.250 kg / (0.05 m)3 density = 0.250 kg / 0.000125 m3 density = 2000 kg/m3 (For comparison, pure water's density is about 1000 kg/m3)
What would change if you smashed a marshmallow mass volume or density?
Marshmallows vary in density. They are not a pure substance. As they contain air bubbles their density can be altered merely by squeezing them as can their volume but their mass would be the same even if smashed into pieces. The marshmallow's physical dimensions would change.
What is the mass of 1.2L of water?
Pure water at standard temperature and pressure has density of 1 kg/L.1.2 Liter = 1.2 kg
What is the mass in grams of 6ml of water?
Approximately 6g. The density of pure water at 20 degrees centigrade and standard atmospheric pressure is 1 g/ml. The answer is approximate since the water may not be chemically pure and you do not give a temperature or pressure.
Compute the density of an 820g sample of pure silicon occupying a 350cm3 container?
Density= mass/volumeDensity=820g/350cm3Density= 2.34g/cm3
A sample thought to be pure lead occupies a volume of 15.0 mi.and has a mass of 160.0g.determine the density and is the sample pure lead?
The density is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.
Compute the density of an 820g sample of pure silicon occupying a 350 cm3 container?
2.34285714g/cm3

The idea is to divide the mass by the volume.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
What is the mass of a 350 cm3 sample of pure silicon with density of 2.336 gcm3?
Start by writing the formula that you probably know for density D=m/V Now plug in the data that you have: 2.336 g/cm3 = m/350 cm3 so, m = 350 x 2.336 = 817.6 g
a scientist has a sample of a substance with a volume of 50cm cubed and a mass of 135g. this is most likely a sample og which substance gold, pure water, aluminum or ocean water?
The **density** of a substance is defined as its mass per unit volume. We can calculate the density using the formula: [ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} ] Given that the sample has a volume of **50 cm³** and a mass of **135 g**, let's determine the density: [ \rho = \frac{135 , \text{g}}{50 , \text{cm³}} ] The calculated density is approximately **2.7 g/cm³**[^10^]. Now let's compare this value to known densities: **Gold**: Gold has a density of *19.3 g/cm³*⁷. The sample's density is significantly lower. **Pure Water**: The density of pure water is approximately **1 g/cm³** at 4.0°C (39.2°F) . The sample's density is higher than water. **Aluminum**: Aluminum has a density of *2.7 g/cm³*[^10^]. The sample's density matches that of aluminum. **Ocean Water**: Ocean water contains dissolved salts, which increase its density. Seawater density typically ranges from *1.02 g/cm³ to 1.03 g/cm³*. The sample's density is higher than seawater. Based on the calculated density, the sample is most likely **aluminum**.
A cubic centimeter of pure water at maximum density has a mass of?
A cubic centimeter of pure water at maximum density has a mass of what?
How could you determine is a sample of gold is pure?
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
How could you determine if a sample gold is pure?
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
How many moles in 31.78G of Boron?
The atomic mass of B is 10.8Amount of B = mass of pure sample/molar mass = 31.78/10.8 = 2.94mol There are 2.94 moles of the element boron in a 31.78g pure sample.
What is the density of 100 gram of water?
The density of water at standard temperature and pressure is 1 gram/milliliter. The size of the sample is irrelevant. If the sample is pure, then one drop of it has the same density as a tankerful of it has.
