Which balance is more precise if the mass of something is actually 12.1G which balance is more accurate?
The balance that shows the mass as 12.1g is more accurate. Accuracy refers to how close a measurement is to the actual value, while precision refers to how consistent a measurement is when repeated. In this case, the balance that displays 12.1g is both accurate and precise.
What is the molar absorptivity of CuSO4 and how does it impact the measurement of its concentration in a solution?
The molar absorptivity of CuSO4 is a measure of how well it absorbs light at a specific wavelength. It impacts the measurement of its concentration in a solution by affecting the amount of light absorbed, which is used to determine the concentration through a calibration curve. A higher molar absorptivity means more light is absorbed, leading to a more accurate concentration measurement.
Explain why significant figures represent the precision of a measurement and not its accuracy?
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
Why is a 10ml graduated cylinder more accurate than a 100ml graduated cylinder?
A 10ml graduated cylinder is more accurate than a 100ml graduated cylinder because the smaller volume allows for more precise measurements. The smaller increments on the scale of a 10ml cylinder result in smaller margin of error compared to a 100ml cylinder. This enhances the accuracy of measuring small volumes with greater precision.
Why would a scientist use a graduated cylinder instead of beaker?
A Volumetric Pipette is the most accurate and used for titration calculations, if you include that as a type of pipette then it is FAR more accurate than a graduated cylinder. A beaker is very inaccurate so don't even go there.
Is a measurement of centimeters more accurate than with inches?
Yes.
Why are millimeters more accurate than centimeters?
Because they are smaller units of measurement.
Why do doctors measure in centimeters insted of inches?
Because it is more accurate
What is more accurate a measurement given in centimeters or millimeters?
Millimeters are smaller so if a measurement is given in mm it is likely to be more accurate than a measurement given in cm. However, it's important to note that neither mm nor cm is inherently more accurate.
Why is millimeters more accurate than centimeters?
Millimeters are more accurate than centimeters because they are smaller units of measurement, allowing for more precise measurements. Since there are 10 millimeters in a centimeter, using millimeters as the standard unit provides a more detailed measurement scale.
Do they measure pre-born babies with inches or centimeters?
Pre-born babies are typically measured in centimeters during prenatal ultrasounds. This is because centimeters provide a more precise measurement compared to inches.
Why should you measure a leaf with centimeters?
Centimeters are more accurate then inches, so you're less likely to mess up the measurements.
What is most accurate 178 inches or 12 feet?
That depends whether the thing you're measuring is closer to 178 inches or 12 feet.However, if you round to the nearest measurement, a measurement of 178 inches can be within 2.54 centimetres of accuracy, while a measurement of 12 feet can be within 15.24 centimetres of accuracy - therefore making inches a much more accurate measurement.
What mecerment is equl to 14?
The measurement equal to 14 can vary depending on the context. For example, in terms of length, 14 inches is equivalent to 35.56 centimeters. If referring to weight, 14 ounces is equal to 396.89 grams. Please specify the type of measurement for a more accurate conversion.
How long is 230 cm in inches?
The answer is 90.55 inches (approx.). Inches and centimeters are both units of linear measurement. Inches are used in the imperial system whereas centimeters are used in the metric system. To convert from cm to inches, multiply the cm unit by 0.393701.230 cm = 90.6 in (a little more than 7.5 feet)
Do you use centimeters or millimeters in a rain gauge?
Rain gauges typically use millimeters to measure rainfall because they provide a more precise measurement due to the smaller unit of measurement compared to centimeters. This allows for more accurate tracking of rainfall amounts.
What is 7 cm to the nearest 10th of a centimeter?
Impossible to say. What you have is a measurement in whole centimeters. Those are bigger than tenths of centimeters. A less accurate measurement. And you can't make a more accurate measurement out of a less accurate one. The other way is fine though. Measured with tenths, anything between 6.6 - 7.4 cm could be written as 7 cm according to the laws of rounding.
