Answer:
Explanation:
From the given information:
mass = 3.42 kg = 3420 g
molar mass of [tex]C_3H_7NH_2[/tex] = 59 g
Number of moles of [tex]C_3H_7NH_2 = \dfrac{mass (in gram) }{molar mass}[/tex]
Number of moles of [tex]C_3H_7NH_2 = \dfrac{3420 \ g }{59 \ g}[/tex]
= 57.966
number of hydrogen atoms present = [tex]n \times N_A[/tex]
where;
[tex]N_A = avogadro's \ constant = 6.022 \times 10^{23}[/tex]
number of hydrogen atoms present [tex]=9 \times 57.966 \imes 6.022 \times 10^{23}[/tex]
[tex]\mathbf{= 3.14 \times 10^{26}}[/tex]
