Calculate the number of moles in each sample. Express your answer with the appropriate units.
71.5 g HCCl3
10.7 g C6H12O6
21.6 kg C2H2
22.5 g of nitrogen dioxide
The number of moles of each sample can be calculated as
Number of moles=mass/molar mass
Weight of the chloroform is 71.5g
Molar mass of the chloroform is 199.38g/mol
The number of moles of chloroform= 71.5g/199.38g/mol
= 0.3586 moles.
Weight of the C6H12O6 is 10.7g
Molar mass of the C6H12O6 is 180.156g/mol
The number of moles of C6H12O6= 10.7g /180.156g/mol
= 0.0593 moles.
Weight of the C2H2 is 21.6kg
= 21.6 *1000
Molar mass of the C2H2 is 26.04g/mol
The number of moles of C2H2= 21600g /26.04g/mol
