There are four significant figures in the measurement 1.050 L.
There are 2 significant figures--the two fours. Placeholder zeroes are not significant.
Four of them.

It already is rounded to three significant figures.
The most accurate answer is 0.2 mol/kg.Related Information:The number of significant figures in the final answer must be based on the given with the least number of significant figures which is 2L.
Density= mass/volume. D= 3.0g/1.0L D= 3.0g/L Make sure you write 3.0g/L and not just 3 so that you have the right number of significant figures. Also, make sure that your instructor wants the answer in g/L because density is usually measured in g/mL.
You solve this using the ideal gas law: PV = nRT and solve for n (moles)n = PV/RT = (2.62 atm)(47.8 L)/(0.0821 Latm/Kmol)(775K) n = 1.97 moles (3 significant figures)
1,000 L to 2 s.f., or 1,000 (2 s.f.) or 1,000 L.
There are 3 significant figures in this measurement.
There are 3.
There are three.
Four.

4 of them.
Significant figures are calculated using various rules.ÊAll non-zero numbers are significant and all zeros that are to the right of the decimal point as well as at the end of a number are significant.ÊTherefore, 1.050L has 4 significant figures.
0.0004 has one significant figure.
98.5 L
When divided by a calculator 45.67kg/3.42L equals 13.35 kg/L. Of the two quantities the highest common certainty we have is the 3 significant figures from the volume. Therefore the answer would be 13.4 kg/L rounded to three places.

Assuming that the last 0 is not there purely to use up ink, 4 sig figs.
