Question

Guys please solve 2nd question you will get the answer the 3.2 gram..​

Answer 1

Answer:

rom eqn we can say ...2 mole hydrogen with 1 mole oxygen gives 2 mole water

so 2 mole water  is 36 gram

Explanation:we have 0.1 mole carbon dioxide and 0.1 mole carbon

so from eqn we can say we need 0.1 mole oxygen =3.2g

3. 1 mole oxygen gas is 32 g  

64 gram has 4 mole oxygen atom so 24*10^23 atoms

nitrogen molecule is 14 gram (1 mole) given is 10 mole

so 2*10*6*10^23=1.2*10^25
