Answer:
Number of moles = 0.99 mol
Explanation:
Given data:
Mass of potassium chloride = 74 g
Number of moles of potassium chloride = ?
Solution:
Formula:
<em>Number of moles = mass/molar mass</em>
Molar mass of KCl = 74.6 g/mol
now we will put the values in formula:
Number of moles = mass/molar mass
Number of moles = 74 g/ 74.6 g/mol
it is C it splits atoms
mass (m) = ? , volume = 18.0 ml , density = 1.42 g/ml .
I hope I helped you^_^
