How many significant figures are there in the number 0.04560700?
7 sigfigs
How many sigfigs does 16.00?
It has 4. Every 0 after a decimal and after a significant digit is significant.
How many sigfigs are in 0.0050?
The number 0.0050 has three significant figures. The leading zeros (0.00) are not counted as significant, while the digits 5 and 0 are significant. The trailing zero after the 5 indicates precision in the measurement.
How many sig figs in 100?
There are 3 sigfigs in 100. because there is a decimal after the second zero, indicating that the units digit matters. If there is no decimal place, then the zeros are considered place holders and thus would be 1 sig fig only. But since there is a decimal, the former is true.
Why is the use of scientific notation important to chemistry?
Scientific notation is useful because it helps to read values' significant figures (sigfigs). For example, the number: 6.02^(-10) is much easier to read than .000000000602. When dealing with especially large or small quantities, scientific notation makes it easier to understand how big or small the quantity is.
How many sigfigs are in 3.0000?
Five.
How many significant figures are there in the number 0.04560700?
7 sigfigs
How many significant figures in 120.0?
if you write it as 1200. (with the decimal) it will have 4 sigfigs.. or it can have 2 sigfigs (12) - im trying to get 3 sigfigs.. that's my hw but i cant get it yet
How many significant figures are in the number 0.032040?
5 of them.
How many sigfigs does 16.00?
It has 4. Every 0 after a decimal and after a significant digit is significant.
1560000.0 has how many sig figs?
you'll notice that there is a decimal, and a zero after the decimal, meaning that the number of sigfigs equals the number of digits: 8
How may Sigfigs does the following have 176g plus 92800 plus 00087 equals 1104g and 10400mi divided by 328102hr equals 317mi over hr?
it supposed to read 17.6g(3 sigfig) + 92.800g(5 sigfigs) +0.0087g(2 sigfigs) = 110.4 another example would be 10400 mi (3 sigfigs) / 3.28* 10^2hr (3 sigfigs) = 31.7 and (21.4 * 7.35)-63.44=157.29-63.44=93.85 but writen as 94
How many significant figures are there in 630000000?
2. The 6 and the 3 are both sigfigs. Since there's no decimal point, the other zeros are placeholders and therefore not important.
How many sigfigs are in 0.0050?
The number 0.0050 has three significant figures. The leading zeros (0.00) are not counted as significant, while the digits 5 and 0 are significant. The trailing zero after the 5 indicates precision in the measurement.
How many sig figs in 100?
There are 3 sigfigs in 100. because there is a decimal after the second zero, indicating that the units digit matters. If there is no decimal place, then the zeros are considered place holders and thus would be 1 sig fig only. But since there is a decimal, the former is true.
How many sig figs in 0.85?
two. Here are some rules for determining sigfigs:Digits from 1-9 are always significant.Zeros between two other significant figures are always significantOne or more additional zeros to the right of both the decimal place and another significant figure are significant.Zeros used solely for spacing the decimal point (placeholders) are not significant.eg.NUMBER SIG FIGS EXPLANATION453 kg3All non-zero digits are always significant.5057 L4Zeros between 2 sigfigs are significant.5.003Additional zeros to the right of decimal and a sigfigs are significant.0.0071Placeholders are not significant
If the wave length is 4mm and the constant is 1.54 mm per microsec what is the freq?
4mm / (1.54mm/us) = 1 sound wave every 2.5974us. 1,000,000us per second. 1,000,000/2.5974 = [385,000Hz] With proper sigfigs = 4 x 10^5 (if the values given here are exact)
