How many moles are present in 234g of NaCl?
1 mole NaCl = 58.443g NaCl 234g NaCl x 1mol NaCl/58.443g NaCl = 4.00 moles NaCl
How many grams are in 0.160 mole of sodium chloride?
1 mole NaCl = 58.44g 0.1601mol NaCl x 58.44g NaCl/mol NaCl = 9.35g NaCl
What chemical formula for table salt?
NaCl It is a rock salt an ore for sodium
How many grams of sodium chloride are in 3 x 10 to the 25 formula units of sodium chloride?
1 mole NaCl = 58.443g NaCl = 6.022 x 1023 formula units NaCl 3 x 1025 formula units NaCl x 1mol NaCl/6.022 x 1023 formula units NaCl x 58.443g NaCl/mol NaCl = 2911g NaCl = 3000g NaCl (rounded to 1 significant figure)
2 Predict and explain what systems are electrically conducting a solid NaCl b molten NaCl c An aqueous solution of NaCl?
molten NaCl and An aqueous solution of NaCl will be conducting due to the presence of free ions in these.
What is the expected value for 'i' for NaCl?
2
What is the Ksp of NaCl?
This value is 36.
Is the expected value the same as the standard deviation?
No. The expected value is the mean!
What is the meaning of expected value in a probability distribution?
The expected value is the average of a probability distribution. It is the value that can be expected to occur on the average, in the long run.
What is the Ksp value for NaCl at room temperature?
This value is approx. 36.
How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.
What is the mean of a normal distribution?
It is the expected value of the distribution. It also happens to be the mode and median.It is the expected value of the distribution. It also happens to be the mode and median.It is the expected value of the distribution. It also happens to be the mode and median.It is the expected value of the distribution. It also happens to be the mode and median.
Difference between mean and expected value?
For a population the mean and the expected value are just two names for the same thing. For a sample the mean is the same as the average and no expected value exists.
What is the expected value of the sum of the number that appears when a pair of fair dice is rolled?
The expected value is 7.
The expected value is what kind of aspect of how probability distribution is characterized?
Expected value is the outcome of confidence of how probability distribution is characterized. If the expected value is greater than the confidence interval then the results are significant.
What does it mean if you get a negative number when you calculate for percent error?
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
What is the expected value of the standard normal distribution equal to?
The expected value of the standard normal distribution is equal to the total amount of the value. It is usually equal to it when the value works out to be the same.
