Question

Answer 1

Câu 1:

a,\(n_{Fe}=\dfrac{28}{56}=0,5\left(mol\right)\)

b,\(m_{H_2O}=0,25.18=4,5\left(g\right)\)

c,\(n_{N_2O}=\dfrac{3,3}{44}=0,075\left(mol\right)\Rightarrow V_{N_2O}=0,075.22,4=1,68\left(l\right)\)

d,\(n_{CH_4}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\Rightarrow m_{CH_4}=0,25.16=4\left(g\right)\)

Answer 2

Câu 2:

a,\(n_{H_2SO_4}=\dfrac{4,9}{98}=0,05\left(mol\right)\)

b,\(m_{Na_2CO_3}=0,2.106=21,2\left(g\right)\)

c,\(n_{CO_2}=\dfrac{95,48}{44}=2,17\left(mol\right)\Rightarrow V_{CO_2}=2,17.22,4=48,608\left(l\right)\)'

d,\(V_{CO_2}=0,25.22,4=5,6\left(l\right)\)

Answer 3

Tách nhỏ ra nhé

Answer 4

Câu 3:

a,\(V_{O_2}=0,2.22,4=4,48\left(l\right)\)

b,\(n_{Cl_2}=\dfrac{2,8}{22,4}=0,125\left(mol\right)\)

c,\(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\Rightarrow V_{SO_2}=0,1.22,4=2,24\left(l\right)\)
