What is 1042 L rounded off to two significant digits?
To write 1042 L to two significant figures, you'll need to use scientific notation. It can't be 1000 L, because that has only one significant figure, because trailing zeros with no decimal point are not significant. To write 1042 L to two significant figures, you need to write it as 1.0 × 10³ L.
What is 98 rounded to 1 significant figure?
It already is rounded to three significant figures.
What is the concentration of a solution of 24g of table salt dissolved in 2 L of water?
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.
What is the density of an object that has a mass of 3.0g and occupies a volume of 1.0l?
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.
How many moles of the gas are in the container with a gas in a closed container has a pressure of 2.62 ATM a volume of 47.8 L and a temperature of 775 K.?
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)

When the measured quantity 45.67 kg is divided by the measured quantity 3.42 L the answer should have how many significant figures?
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.
How many significant figures are in the measurement of 1.050 L?
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.

98.5 L
What is the proper number of significant figures for 7800 L?
The proper number of significant figures for 7800 L depends on how the number is presented. If it is written as 7800 with no decimal point, it typically has three significant figures. However, if it were written as 7800. or in scientific notation (e.g., 7.8 × 10³), it would have four significant figures. To determine the exact number of significant figures, additional context or notation is required.
What is the sum of 6.210 L and 3 L expressed in the correct number of significant figures?
9
What is the number of significant figures in 0.0004 L?
The number of significant figures in 0.0004 L is 1. In scientific notation, trailing zeros to the right of the decimal point are considered significant. Therefore, in this case, only the non-zero digit (4) is significant.
