Answer: 30.72 moles of
will be produced from 5.12 moles of glucose.
Explanation:
The balanced chemical equation for combustion of glucose is:
According to stoichiometry :
1 moles of glucose produce = 6 moles of
Thus 5.12 moles of glucose produce =
of
Thus 30.72 moles of
will be produced from 5.12 moles of glucose.
Answer:
6. d, 7. a
Explanation:
6. Molarity is a number of moles solute in 1 L solution.
7. 1 L solution - 2.5 mol K2CO3
20 L - x mol K2CO3
x =20*2.5/1 = 50 mol K2CO3
Molar mass(KCO3) = M(K) + M(C) + 3M(O)= 39 +12 +3*16= 99 g/mol
99 g/mol *50 mol = 4950 g KCO3 Closest answer is A.
Actually KCO3 does not exist, in reality it should be K2CO3.
