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 samples of silver and lead each had volumes equal to 1 cm3 which sample would have the greater mass What would the difference in the masses be?
Silver has a density of approximately 10.49 g/cm³, while lead has a density of about 11.34 g/cm³. Since both samples have the same volume of 1 cm³, the lead sample would have a greater mass than the silver sample. The mass of the lead sample would be about 11.34 grams, while the mass of the silver sample would be about 10.49 grams, resulting in a difference of approximately 0.85 grams.
If a sample of silver and lead each had volumes equal to 1cm3 which sample would have the greater mass What would the difference in the masses be?
Silver has a density of approximately 10.49 g/cm³, while lead has a density of about 11.34 g/cm³. Therefore, the lead sample, with a volume of 1 cm³, would have a greater mass than the silver sample. Specifically, the mass of the silver would be about 10.49 grams, while the mass of the lead would be around 11.34 grams, resulting in a difference of approximately 0.85 grams.
What is the volume of a container that contains 14.3 of a substace having a density of 0.988?
To find the volume of the container, you can use the formula: volume = mass / density. Given that the mass of the substance is 14.3 grams and the density is 0.988 grams per cubic centimeter, the volume would be calculated as follows: Volume = 14.3 g / 0.988 g/cm³ ≈ 14.48 cm³. Thus, the volume of the container is approximately 14.48 cubic centimeters.
How many moles of a substance are present in a sample if the sample weighs 5 grams and the molar mass of the substance is 30 g/mol (Dalton to moles conversion)?
To find the number of moles in a sample, divide the sample's weight by the molar mass of the substance. In this case, if the sample weighs 5 grams and the molar mass is 30 g/mol, the number of moles present in the sample would be 0.167 moles.
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.
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.
