Explanation:
The empirical formula is Fe₃O₄.
The empirical formula is the <em>simplest whole-number ratio of atoms</em> in a compound.
The ratio of atoms is the same as the ratio of moles, so our job is to calculate the molar ratio of Fe to O.
I like to summarize the calculations in a table.
<u>Element</u> <u>Moles</u> <u>Ratio</u>¹ <u>×3</u>² <u>Integers</u>³
Fe 0.77 1 3 3
O 1.0 1.3 3.9 4
¹ To get the molar ratio, you divide each number of moles by the smallest number (0.77).
² If the ratio is not close to an integer, multiply by a number (in this case, 3) to get numbers that are close to integers.
³ Round off these numbers to integers (3 and 4).
The empirical formula is Fe₃O₄.
A rectangle box measures 6.00 in. in length, 7.00 in. in width, and 8.00 in. in height. The volume of the rectangular box is 5.506 L
Given,
1 inch = 2.54 cm
Length = 6.00 inches = 6.00 x 2.54 cm = 15.24 cm
Width = 7.00 inches = 7.00 x 2.54 cm = 17.78 cm
Height = 8.00 inches = 8.00 x 2.54 cm = 20.32 cm
Now,
Volume of rectangular box = Length x Width x Height
= 15.24 cm x 17.78 cm x 20.32 cm
= 5506.05 cm3
= 5506.05 mL (\small \because 1 cm3 = 1 mL)
= 5.506 L (\small \because 1000 mL = 1 L)
Hence, the volume of rectangular box is 5.506 L.
