1 mole is 6.02x 10^23 molecules
3 * 6.02*10^23 =1.806*10^24 molecules
Answer:
Isotopes of bromine have same chemical properties because they have same number of electrons.
Isotopes have only different number of mass that does not affect it's chemical properties too much.
Answer:
0.04 mol
Explanation:
Given data:
Mass of barium = 5.96 g
Moles of barium = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of barium = 5.96 g/ 137.33 g/mol
Number of moles = 0.04 mol
Thus the number of moles of barium in 5.96 g are 0.04 moles. The chemist weight out the 0.04 moles .
