What else can I help you with?
A sample has a mass of 35.4 g and a volume of 36.82 mL What is the density of the sample?
The density of the sample can be calculated by dividing the mass of the sample (35.4g) by its volume (36.82 mL). Density = Mass/Volume Density = 35.4g / 36.82 mL Density = 0.962 g/mL
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
A sample has a mass of 612 grams and a volume of 78 cm3 What is the identity of the sample?
To determine the identity of the sample, you would need the density of the material it is made of. Density is calculated by dividing mass by volume (density = mass/volume). Without this information, it is not possible to accurately determine the identity of the sample.
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 sample divided by its volume?
Its density. Density is mass per unit volume.
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
What is the density of a sample that has mass of 77.0 g and a volume of 36 mL?
The density of the sample is about 2.14 g/mL
A sample has a mass of 35.4 g and a volume of 36.82 mL What is the density of the sample?
The density of the sample can be calculated by dividing the mass of the sample (35.4g) by its volume (36.82 mL). Density = Mass/Volume Density = 35.4g / 36.82 mL Density = 0.962 g/mL
What is the density of a mineral sample?
The density of a mineral sample is a measure of its mass per unit volume. It can be calculated by dividing the mass of the sample by its volume. The density of a mineral sample is a characteristic property that can help in identifying the mineral.
How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.

What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
How does halving the sample affect the density?
Not at all. The density remains the same.
The density of lead is 11.4 gcm3 at 20 and degC. A chemist has a metallic sample that is either pure lead or mostly lead. If the density of the sample is 11.0 gcm3 at 20 and degC then the sample most?
The sample is likely not pure lead, as its density of 11.0 g/cm³ is lower than the density of pure lead, which is 11.4 g/cm³. This suggests that the sample may contain other metals or impurities that decrease its overall density. Therefore, it can be concluded that the sample is mostly lead but is not pure lead.
How would you determine the density of a powdered dry sample which soluble in water?
1. Apparent density: - weight a graduated cyllinder - put the sample in the graduated cyllinder up to a given volume (note this volume) - weight the graduated cyllinder with the sample - calculate the mass of the powder by difference - the density is the ratio mass of the sample/volume of the sample 2. True density of a powder: you need a helium pycnometer.
