Question

calculate the number of moles of HCL when 73 grams of HCL are dissolved in 1 litre of water​

Answer 1

Answer:

The number of molecules in 73g of HCL Get the answers you need, now! ... 1 g atom of HCl =1 mole = molecular mass =36.5 g ... According to Avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number of particles. To calculate the moles, we use the equation:-

Explanation:

Answer 2

Explanation:

Answer: 12.05\times 10^{23}12.05×10

molecules

Explanation:

According to Avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number 6.023\times 10^{23}6.023×10

23

of particles.

To calculate the moles, we use the equation:-

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}Number of moles=

Molar mass

Given mass

\text{Number of moles}=\frac{73g}{36.5g/mol}=2molesNumber of moles=

36.5g/mol

73g

=2moles

Now 1 mole of HClHCl molecule contains = 6.023\times 10^{23}6.023×10

molecules

2 moles of HClHCl contains = \frac{6.023\times 10^{23}}{1}\times 2=12.04\times 10^{23}
