Ca: 40.078 g/mol
C: 12.011 g/mol
O: 16.00g/mol
CaCO3:
molar mass of 100.089g/mol
Answer:
n C2H5OH = 0.2496 mol
Explanation:
- moles (n) = mass / molecular weight
∴ m C2H5OH = 11.5 g
∴ Mw C2H5OH = (2)(12.011) + (6)(1.00794) + 15.9994 = 46.069 g/mol
⇒ n C2H5OH = (11.5 g)/(46.069 g/mol) = 0.2496 mol C2H5OH
Answer:
Carbon dioxide is a chemical compound composed two oxygen atoms covalently bonded to one carbon atom. Carbon dioxide's molecular shape is linear. Also carbon dioxide exists in Earth's atmosphere as a gas. Carbon Dioxide- CO2 makes up one of the gases in our atmosphere.
