If the atomic mass of lithium is 6.941 and it exists as lithium-6 and lithium-7 what percent of the isotope is lithium-7?
To determine the percentage of lithium-7, we need to calculate the relative abundance of each isotope considering their atomic masses. Given that the atomic mass of lithium-6 is 6.015 and that of lithium-7 is 7.016, the percentage of lithium-7 is approximately 92.5% based on natural abundance.
How many significant figures do 14500?
The number 14500 has five significant figures. Significant figures are the digits in a number that carry meaning contributing to its precision. In this case, all the digits in 14500 are considered significant because they are all non-zero and are part of the measurement.
How many significant figures are there in the measurement 3300g?
2 Except that the fact that the figure is given as 3300 g instead of 3.3 kg suggests that the trailing 0s are significant.
How many significant figures are in 0.00200?
To assess how many significant figures a number has been given to, you first need to find the greatest non-zero digit. In this case that is the 2. The next step is to count how many digits have been given after this one. In this case there are no more. Thus the figure 0.002 is to 1 significant figure.
Why are significant figures important when reporting measurements?
Significant figures are important because they indicate the precision of a measurement. They help convey the uncertainty in a measurement and ensure that the reported value reflects the limitations of the measuring tool. Using the correct number of significant figures also promotes consistency and accuracy in scientific communication.
What is the significant figures of the number of 23.400?
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
