Volume
The greatest possible error for the measurement 0.991 g would be half of the smallest measurable unit, which is typically 0.001 g for this measurement. Therefore, the greatest possible error would be ±0.0005 g.
There are 2 significant figures in this measurement.

The correct unit of measurement for 0.1 g is grams (g). This value indicates a mass measurement and is commonly used in scientific and culinary contexts. To express it in different forms, it can also be written as 100 milligrams (mg).
The error in the measurement was 7.5 g. This was calculated by subtracting the estimated mass (35 g) from the actual mass (42.5 g).
A mass measurement expressed as 4.6 g ± 0.2 g indicates that the measured mass is 4.6 grams, with an uncertainty of 0.2 grams. This means the true mass could range from 4.4 grams to 4.8 grams. The "± 0.2 g" reflects the precision of the measurement, highlighting the potential variation due to factors like instrument limitations or measurement techniques.
The term "12 g" typically refers to a measurement of mass or weight, indicating that an object weighs 12 grams. The gram is a unit of measurement in the metric system, commonly used to quantify small amounts of mass, such as food ingredients or laboratory samples. In various contexts, "g" can also denote gravitational acceleration, but in this case, it most likely denotes grams.
