A compound has a chemical composition of 97.6 g carbon, 4.9 g hydrogen, 52 g oxygen, 45.5 g nitrogen. What is the empirical form
Alekssandra [29.7K]
First  step  is  to  calculate  the  mole  of each   element
that  is;
carbon  97.6/12=8.13moles
hydrogen= 4.9/1=4.9  moles
oxygen 52/16=3.25  moles
nitrogen=45.5/14=3.25 moles

step  two  is  to  calculate  the mole ratio  by   dividing with  the  smallest  number of  moles
that  is  divide  each  mole  with  3.25moles
 carbon=8.13/3.25 =5/2
hydrogen=4.9/3.25= 3/2
oxygen=3.25/3.25=1
nitrogen=3.25/3.25=1
step  3;  multiply  all  the  mole  ratio by  2  to  remove  the  fraction
carbon=5/2  x2 =5
hydrogen=3/2 x2=3
oxygen=1 x2=2
nitrogen  =1x2=2
therefore  the  empirical  formula  is C5H3O2N2(answer c)

A liquid sample, with a density of .0915 g/mL has a mass of 17.7 grams.
Arlecino [84]

The relation between density, mass and volume is

Density = \frac{Mass}{Volume}

1) to calculate = volume

given:

Density = 0.0915 g/ mL

mass = 17.7 grams

formula used:

Density = \frac{Mass}{Volume}

Thus

Volume Volume = \frac{Mass}{Density} = \frac{17.7 g}{0.915 \frac{g}{mL} }  = 193.44 mL

Answer: 193.44 mL

2) the mass of sample will be

mass = density X volume = 0.0915\frac{g}{mL} X 76.5 mL = 6.99 = 7 g

Answer: 7 g
