Atomic mass C = 12.0107
Atomic mass O= 15.9994
Calculate the molecular mass of the CO2
12.0107 + (2 x 15.9994) = 44.0095
Multiply the mass of CO2 by the conversion factor that relate the O mass to the molecular mass of CO2 to find the mass of O in the 71.89g of CO2
71.89 g CO2 x (2 x 15.9994) / 44.0095 =
52.2703900748702
52.27 g O
Answer:
Explanation:
Well you didn’t send a picture of the question but h2O is water so. If the questions answer has a option of water then pick that one
M (C2H6) = n × M = 4.6 × 30 = 13.8 g.
Answer:
4.94x10^24 atoms Zn
Explanation:
By definition, there are 6.022x10^23 atoms in a mole of a substance. This is a conversion factor:
(6.022x10^23 atoms/mole)
(8.2 moles Zn)* (6.022x10^23 atoms/mole) = 4.94x10^24 atoms Zn
