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
Number of moles = 0.99 mol
Answer:
Electrons, Protons, and Neutrons. ... Protons are another type of subatomic particle found in atoms. They have a positive charge so they are attracted to negative objects and repelled from positive objects. Again, this means that protons repel each other
