Answer: The empirical formula is ![MgSO_3](https://tex.z-dn.net/?f=MgSO_3)
Explanation:
Mass of Mg= 46.6 g
Mass of S= 61.4 g
Mass of O = 92.0 g
Step 1 : convert given masses into moles.
Moles of Mg =
Moles of S =
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For Mg =
For S=
For O =
The ratio of Mg: S: O = 1: 1: 3
Hence the empirical formula is

constant speed or a horizontal line is an rest

Answer:
34.32 oz
Explanation:
1.- The carpet has the dimension 12 x 11 ft, so it has an area = 12 x 11 = 132 ft2
To convert the Ft2 into yd2:
9 ft2 = 1 yd2
132 ft2 = x X = (132 x1) / 9 = 14.6 yd2
2.- By now, it is now that the 39 % is burned, so obtain the 39 % of 14.6 yd2
14.6 yd2 = 100 %
x = 39 % x = (39 x 14.6) / 100 = 5.72 yd2
3.- It is known that 30 oz acrylan /yd2
30 oz = 1 yd2
x = 5.72 yd2 X = (5.72 x 30) /1 = 171.6 oz
4.- It is assume that just the 20 % of the fibers has HCN
171.6 oz = 100 %
x = 20 % X = (20 x 171.6) /100 = 34.32 oz
