Answer: The mass of produced is, 149 grams.
Explanation : Given,
Mass of = 354.2 g
Molar mass of = 278 g/mol
Molar mass of = 58.5 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 3 moles of react to give 6 mole of
So, 1.27 moles of react to give mole of
Now we have to calculate the mass of
Therefore, the mass of produced is, 149 grams.
1 foot = 30.48 cm
3.5 ft * 30.48 cm = 106.68 cm
Answer = 106.68 cm

Well, the molar mass of acetone would be
3(12.011)+6(1.008)+15.999 , which cleans up to be 58.08 grams.
out of this total, 3(12.011), or 36.033 grams are carbon
So, to find the percent, you do part over whole
36.033/58.08, which equals 0.6204 with significant figures
multiply that by 100 to get 62.04%
Hope that helps!
