How many molecules are in 25 g of HCI? Thank you :)

Step-by-step explanation:

To calculate the number of molecules first find the number of moles then multiply it by 6.02×10^23

number of moles(n) = mass / molar mass (M)

M of HCl = 1 + 35. 5 = 36.5g/mol

n = 25/36.5 = 0.6849mol

next we use the formula

N = n × L

N = number of entities

n = number of moles

L = Avogadro's constant 6.02 × 10^23 entities

Number of HCl molecules is

0.6849 × 6.02 × 10^23

Hope this helps you
