The frequency decreases 16-fold
Explanation:
Answer:
mass = 0.2982 grams
Explanation:
Given that;
volume = 100.0 mL = 0.1 L
Molarity =0.040 M
Since Molarity =
(x) no of moles = 0.040 × 0.1
= 0.004 moles
Also; to calculate the mass of KCl should you weigh to make this solution;
we have;
no of moles =
molar mass of KCl = 74.55 g/mol
∴
0.004 moles =
mass = 0.004 moles * 74.55
mass = 0.2982 grams
Hence, the mass of KCl should you weigh to make this solution is 0.2982 grams
