1 fluid ounce = 29.57353 mL (to 7 significant digits)
A 100 mL graduated cylinder is graded in divisions of 1 mL giving results which have 2 significant figures. Cylinders for measuring up to 10 mL to have divisions at 0.1 mL, so again giving 2 sig figs.2 digits. .
As many as are required
2 of them.
There are 5 significant figures in this measurement.
Four - zeros between significant digits are significant.

There are six significant figures in 1009.630 mL. The zeros that follow the decimal point and are trapped between nonzero digits are considered significant.
Five, because if they were not significant, the final two 0s should not be there.
All four of them.
No, 3 of them.
157.725 ml is the answer if 0.6667 is an exact measurement. If it's an actual measurement, you only have 4 significant digits of precision, and the answer is 157.7 milliliters.

It is equally wrong to record too many digits, since this implies greater ... Thus, significant figures are those digits that give meaningful but not ... 3.43+8.6=12.0 ... 8 x 10-4 we can calculate the pH from the definition of quantity.
There are two significant figures in 56 mL. The first two digits are considered significant because they are non-zero digits. Zeros at the end of a number without a decimal point are not considered significant figures.
1 litre = 1000 millilitres so 55 litres = 1000*55 = 55000 ml. Simple!
Integers ending in 0 are ambiguous cases. The measurement could be accurate to the units digit and in that case all three digits are significant. But is could be accurate to the nearest ten, in which case, only the first two digits are significant.
