Answer:Propanone is the IUPAC name for acetone, and butanone is the name for ethyl methyl ketone.
Explanation:
<span>1.58x10^-1 moles
To get the number of moles, we simply need to divide by Avogadro's number, which is 6.0221409x10^23. So
9.50x10^22 / 6.0221409x10^23 = ?
Since we're dealing with scientific notation, we will deal with the significand and exponents separately.
To divide, simply divide the significands as you would normally.
9.50 / 6.0221409 = 1.577512077
And subtract the exponent for the divisor from the exponent from the dividend:
22 - 23 = -1
And we now have
1.577512077 x 10^-1 moles.
But that answer has far too many digits given the precision of the data and should only be as precise as the least precise piece of data used. In this problem, we had 8 digits of precision for Avogadro's number and 3 digits of precision for the number of atoms. Of those 2 pieces of data, 3 is the lowest precision and therefore the answer should be rounded to 3 digits, giving 1.58x10^-1 moles.</span>
