A 10 ml sample of a substance has a mass of 20 grams what would be the mass of a 200 ml sample of the same substace?

The second sample is 200/10 = 20 times as large.
So its mass will be 20 times as great ie 20*20 grams = 400 grams.

If a sample contained 1 gram of pure substance A and another test tube contained 4 grams of pure substance A how would the melting point differ and how would the experiment differ?
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
A 4.0 liter sample of gasoline weighs 2700 grams What is the density of the gasoline expressed in the units gram per ml?
Density is calculated by dividing the mass of the substance by its volume. In this case, the density of gasoline would be 2700 grams ÷ 4000 ml = 0.675 grams/ml. So, the density of the gasoline is 0.675 grams per milliliter.
If 1 cc of a substance has a mass of 1.5 grams what is its density?
Density is defined as the amount of matter (mass) per unit of volume of a specific substance, and is calculated by dividing the mass of any sample of the substance in question by its volume. Considering the unit of density as g/cm3 (grams per cubic centimeter or grams per cc), the density of the substance in your question is exactly 1.5 g/cm3.
The volume of a sample of water is 20cm3 the mass of?
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
A scientist has analyzed the chemicals that make of a sample of an unknown substance. Which chemicals would be the best indicator that the unknown substance is a plant?
cellulose and starch
What volume would be occupied by 7.75 g of the substace if the sample occupies 49.6 cm?
I consider this question as erroneous.
How Many Halflife Are These In A 100-year Span How Many Grams Of The Sample Would Remain At The End Of The 100 Years?
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
If a sample contained 1 gram of pure substance A and another test tube contained 4 grams of pure substance A how would the melting point differ and how would the experiment differ?
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
Definition of a hibitory substance relative to a water sample?
A hibitory substance relative to a water sample is a substance that allows for the growth of microorganisms. This would be like a contamination of water that can cause disease to spread.
A 4.0 liter sample of gasoline weighs 2700 grams What is the density of the gasoline expressed in the units gram per ml?
Density is calculated by dividing the mass of the substance by its volume. In this case, the density of gasoline would be 2700 grams ÷ 4000 ml = 0.675 grams/ml. So, the density of the gasoline is 0.675 grams per milliliter.
How much 800ML in grams?
The exact conversion of milliliters to grams depends on the substance being measured. For water, 800 milliliters would be equal to 800 grams. For other substances, you would need to know the density of the substance to convert.
What types of energy would exist in both a solid sample and a gas sample of the same monatomic substance?
kinetic energy from translation
One thousand grams of seawater would consist of how many grams of dissolved substance?
965<nope
How many grams would a sample of 3.01 x 1023 atoms of tellurium be?
To determine the number of grams in a sample of 3.01 x 10^23 atoms of tellurium, you would first convert the number of atoms into moles using Avogadro's number. Then, you would find the molar mass of tellurium and use it to convert moles into grams.
If 1 cc of a substance has a mass of 1.5 grams what is its density?
Density is defined as the amount of matter (mass) per unit of volume of a specific substance, and is calculated by dividing the mass of any sample of the substance in question by its volume. Considering the unit of density as g/cm3 (grams per cubic centimeter or grams per cc), the density of the substance in your question is exactly 1.5 g/cm3.
400 grams are 1 ml?
It would have to be a very dense substance.
The volume of a sample of water is 20cm3 the mass of?
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
