1 How long does it take for an ear piercing to heal? ...I got a second ear piercing at claireâs about two months ago. 2  I kept the earring on for 6 weeks and cleaned it with the antiseptic like they said to.
For instance, suppose we believe our sample is benzene (C 6 H 6). We can compare the following: 1  The empirical formula (CH) obtained from the molecular formula of benzene (C 6 H 6). 2  The empirical formula obtained from a elemental analysis of the sample.o do this, we need to determine the empirical formula from the molecular formula. To determine the empirical formula of a known substance, such as glucose, we take the subscripts of the molecular formula (C 6 H 12 O 6) and reduce then to the simplest whole number ratios. If we divide this by 6, we get C 1 H 2 O 1.
1 The molecular formula of hexane is C6H14. 2  It is mostly a colorless liquid. 3  It has a melting point of roughly -139.54Â°F (-95.3Â°C) and. 4  The boiling point is 154.04Â°F (67.8Â°C). 5  It has a molar mass of 86.18 grams per mole (g/mol). 6  It is also a non-polar molecule, meaning that it is not soluble in water.exaneâs physical properties are eminent. 1  The molecular formula of hexane is C6H14. 2  It is mostly a colorless liquid. 3  It has a melting point of roughly -139.54Â°F (-95.3Â°C) and. 4  The boiling point is 154.04Â°F (67.8Â°C).
