giải chi tiết ra giùm mk luôn nha

Answer 1

[hnamyuh]

a)

$n_{Nito} = \dfrac{6,02.10^{23}}{6,02.10^{23}} = 1(mol)$
$m_{Nito} = 1.14 = 14(gam)$

b)

$n_{Cl} = \dfrac{6,02.10^{23}}{6,02.10^{23}} = 1(mol)$

$m_{Cl} = 1.35,5 = 35,5(gam)$

c)

$n_{H_2O} = \dfrac{6,02.10^{23}}{6,02.10^{23}} = 1(mol)$

$m_{H_2O} = 1.18 = 18(gam)$

Answer 2

[Thảo Phương]

a) \(n_{N_2}=\dfrac{6,02.10^{23}}{6,02.10^{23}}=1\left(mol\right)\)

=> \(m_{N_2}=1.28=28\left(g\right)\)

b)  \(n_{Cl_2}=\dfrac{6,02.10^{23}}{6,02.10^{23}}=1\left(mol\right)\)

=> \(m_{Cl_2}=1.35,5.2=71\left(g\right)\)

c)  \(n_{H_2O}=\dfrac{6,02.10^{23}}{6,02.10^{23}}=1\left(mol\right)\)

=> \(m_{H_2O}=1.18=18\left(g\right)\)

d)  \(n_{CaCO_3}=\dfrac{6,02.10^{23}}{6,02.10^{23}}=1\left(mol\right)\)

=> \(m_{CaCO_3}=1.100=100\left(g\right)\)
