Answer:
<u>Question</u><u> </u><u>1</u><u>:</u>
<em>Answer</em><em>:</em><em> </em>M: (17 - 35) & (17 - 37), N:(8 - 18) (8 - 16) & (8 - 17)
• Isotopes are atoms of the same element with same atomic number but different mass numbers.
<u>Question</u><u> </u><u>2</u><u>:</u>
<em>Answer</em><em>:</em><em> </em>Element M has high nuclear charge than element N
• Nuclear charge depends on atomic number or proton number.
Answer:
The molar mass of H₂O₂ (the solute) in the aqueous solution of
H₂O₂ is 51 g
Explanation:
Given;
H₂O₂ compound
Concentration of aqueous solution of H₂O₂ = 1.5M
The molecular mass of H₂O₂ = (1 x 2) + (16 x 2) = 34 g/mol
Reacting mass (g) = Concentration x Molar mass
Reacting mass (g) = 1.5 x 34
Reacting mass (g) = 51 g
Therefore, the molar mass of H₂O₂ (the solute) in the aqueous solution of
H₂O₂ is 51 g
