Mole number of 75 g is 0.4 mol. NO2 is 0.8 mol and is 36.8 g.
Answer: 1 mol C8H18 produces 9 mol H2O
Explanation: reaction : C8H18 + 12.5 O2 ⇒ 8 CO2 + 9 H2O
Answer:
0.20moles
Explanation:
1 mole Na contains 23 g Na
23 g Na =1 mole of Na
1 g Na= 1/23 moles of Na
4.6 g Na= 1/23×4.6= 4.6/23=0.2 moles
Therefore 0.2 moles are present in 4.6 g of Na
