The rate of effusion of gas B is 728.32 m/s
<u>Explanation:</u>
Given:
Mass of A, m₁ = 46 g/mol
Rate of effusion of A, R₁ = 515 m/s
Mass of B, m₂ = 92 g/mol
Rate of effusion of B, R₂ = ?
We know:
Substituting the value we get:
Therefore, the rate of effusion of gas B is 728.32 m/s

Answer is: tomatoes is thousand (1000) times more acidic than water.
pH(tomato) = 4.00.
pH(water) = 7.00.
pH = -log[H⁺<span>].
</span>[H⁺] = 10∧(-pH); concentration of hydrogen ions.
[H⁺] = 10⁻⁴ M = 0.0001 M; tomato.
[H⁺] = 10⁻⁷ M = 0.0000001 M; water.
[H⁺](tomato) /[H⁺](water) = 0.0001 M ÷ 0.0000001 M.
[H⁺](tomato) /[H⁺](water) = 1000.
