By definition we have that the density is given by:
Where,
M: mass of the sample
V: volume occupied by the sample
Therefore, substituting values in the given equation we have:
Answer:
the density of a sample of gas with a mass of 30 g and a volume of 7500 cm3 is:
The density of the sample of gas is or .
Further Explanation:
Density of any kind of matter is defined as the total mass of that substance present in the volume occupied by it in the region of space.
Example (1) : If we consider equal amounts of tungsten and iron, then tungsten is heavier than iron because tungsten occupies lesser volume or lesser empty spaces inside it for a particular mass as compared to iron. Therefore, tungsten has density higher than that of iron.
Example (2): If we take 2 cubes of similar size (same volume) of tungsten and gold then the cube of gold will be heavier because its density is more than that of tungsten.
Given:
The mass of the sampleof the gas is .
The volume of the sample of the gas is .
Concept:
The density of the substance is defined as the ratio of the mass and volume.
......(1)
Here, is the density of the sample ofthe gas, is the mass of the sample of the gas and is the volume occupied by the gas.
Substitute the value of and in equation (1).
Thus, the density of the sample of gas is or .

Answer:
Before you make a hypothesis, you have to clearly identify the question you are interested in studying. A hypothesis is a statement, not a question. Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen
Explanation:
Before you make a hypothesis, you need to do preliminary research to understand the subject and define the problem. Collect and analyze relevant data and then based on your observations, you can create an educated guess or hypothesis to be tested.
Before you make a hypothesis, there are several important steps you should undertake. Firstly, you need to do some preliminary research. This research can involve reading books, scholarly articles, or trustworthy digital resources about the subject of interest. It is key to understand the subject well before developing a hypothesis. Secondly, you need to clearly define the problem or question you are interested in answering.
Next, make observations and gather data related to the problem. This is often called data collection and may involve conducting surveys, experiments, or fieldwork. After collecting and analyzing all the relevant data, you can formulate a hypothesis. A hypothesis is an educated guess about how things work or a tentative explanation that you will test in your experiment.
