What is the identity of a sample that has a mass of 2.44 g and a volume of 0.34 cm3?
The identity of the sample can be determined by calculating its density, which is mass divided by volume. In this case, the density would be approximately 7.18 g/cm³. By comparing this density to known values for different substances, you can identify the sample based on its density.
A sample of zinc is placed in a graduated cylinder. The initial volume of water= 15.0mL and final volume of water and sample= 24.0mL. Determine the mass of the sample of zinc?

What is the mass of aluminum sample who volume is 10.0 cm3?
27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
Which sample would have a larger volume Suppose that you have two gas samples gas A and gas B . The sample of gas A has twice as many particles as gas B . Which sample would have a larger volume?
The gas A has larger volume (x2).
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
What property like volume depends of the size of the sample?
The property that depends on the size of the sample is extensive. Extensive properties, such as mass and energy, scale with the size of the sample. This means that as the sample size increases, the value of the property also increases proportionally.
Why is volume not always a good way to measure how much mater you have?
Yes, volume is an unreliable measure of the quantity of matter as the same material can have different densities, but the same volume. For example, 1L of ice, water, and steam all contain the same volume of water, but the number of atoms in that volume can vary.
How do you calculate volume of core sample?
The core sample is a cylinder. The volume of any cylinder is (pi) x (radius)2 x (length).
How does halving a sample affect the weight of the sample?
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
What measurement must you make to find the density of a sample of matter?
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.
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.
