What else can I help you with?
All measurements must consist of?
a unit of measurement along with the number
What measurement must you make to find density of a sample of matter?
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
How can the number of significant figures in a measurement be increased without changing the measuring device?
There are at least a couple of ways. Each may not be appropriate in all circumstances.Read the measurement from markings between those that are numbered. For example, most rulers have numbered centimetres but the markings are at millimetres.If there are a number of identical items, then measure then together and take their average. For example, if you have ten identical coins, then the measure their combined mass and divide the answer by 10. That average will have one more sig fig. But the items MUST be identical.
What conditions are necessary when measuring BMR?
When measuring Basal Metabolic Rate (BMR), it's important to ensure the individual is in a fasting state, both physically and mentally at rest, and has not engaged in any strenuous physical activity prior to the measurement. Additionally, the environment should be thermoneutral to prevent any external factors from influencing the metabolic rate measurement.

When a scientist is making a measurement what information must be included with the number?
The measurement units and the degree of precision (significant figures or margin of error).
A neutral with 15 protons must include what else?
15 Electrons. A charge-less (neutral) atom must have an equal number of both protons and electrons, otherwise it becomes an ion.
Why should probability always include a number?
Probability is a numerical value and there must bea number, not just include one.
Would you include zero in finding the mean of a number?
Yes, you MUST.
