Question

Tính số mol của a) 4g NaOH b) 3,7185 L CO₂ đkc c) 1,3046×10²³ ngtử Zn d) 7,3g HCl e) 6,1975 L N₂O đkc

Answer 1

a, \(n_{NaOH}=\dfrac{4}{40}=0,1\left(mol\right)\)

b, \(n_{CO_2}=\dfrac{3,7185}{24,79}=0,15\left(mol\right)\)

c, \(n_{Zn}=\dfrac{1,3046.10^{23}}{6,022.10^{23}}\approx0,22\left(mol\right)\)

d, \(n_{HCl}=\dfrac{7,3}{36,5}=0,2\left(mol\right)\)

e, \(n_{N_2O}=\dfrac{6,1975}{24,79}=0,25\left(mol\right)\)
