Answer:
Find attached the structure of asparthic acid and phenylalanine
Explanation:
9.0 grams will produce 11 L of hydrogen
Mass of NaOH required = 12 g
<h3>Further explanation</h3>
Given
500 ml solution = 0.5 L
Molarity = 0.6 mol / L
Required
mass of NaOH
Solution
Molarity = moles of solute per liter of solution
M = n / V
solute = NaOH
moles of solute = n = M x V
n = 0.6 x 0.5
<em>n = 0.3 moles</em>
Mass of NaOH = mol x MW
mass = 0.3 x 40 = 12 g
CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
