Answer:
72.22 g
Explanation:
975 mL Mercury× 13.5 g/mL = 72.22 g
To convert this first lets see how many meters are in 1 km.
1 km = 1000 meters
Now lets multiply:-
2.7 × 1000 = 2700
So, 2.7 km = 2700 meters.
Hope I helped ya!!
Step 1:
Divide mass of each element with its M.mass in order to find out moles.
C = 63.2 g / 12 g/mol = Moles = 5.26 moles
H = 5.26 g / 1.008 g/mol = Moles = 5.21 moles
C = 41.6 g / 16 g/mol = Moles = 2.6 moles
Step 2:
Select moles of the element with least value and divide all moles of element by it,
C H O
5.26/2.6 : 5.21/2.6 : 2.6/2.6
2.02 : 2.00 : 1
Result:
Empirical Formula = C₂H₂O
