Combustion analysis of an unknown compound provides the following data: 98.28 grams carbon (c), 16.21 grams hydrogen (h), and 65.52 grams oxygen (o). what is the percent composition of carbon in this compound? 6.06% c 54.6% c 33.3% c 36.4% c

Answer : The correct option is, 54.6 %

Explanation: Given,

Mass of C = 98.28 g

Mass of H = 16.21 g

Mass of O = 65.52 g

First we have to calculate the total mass of the compound.

Total mass of compound = Mass of C + Mass of H + Mass of O

Total mass of compound = 98.28 + 16.21 + 65.52 = 180.01 g

Now we have to calculate the percent composition of carbon in the compound.

Formula used :

Now put all the given values in this formula, we get the percent composition of carbon in the compound.

Therefore, the percent composition of carbon in the compound is, 54.6 %

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
