4.305 L = 4.305 × 10^6 µL
1 µL = 10^(-6) L
∴ 4.305 L × [1 µL/10^(-6) L] = 4.305 × 10^6 µL
Answer:
B is the correct answer I think
mol = conc × v
= 1.5 × 0.09
= 0.135 moles of HCl
HCl + NaOH > NaCl + H2O
1 mole HCl = 1 mole NaOH
0.135 mol HCl = x
x = 0.135 mol NaOH
mass = mol × molar mass
= 0.135 × 40
= 5.4 g
NaOH = 23 + 16 + 1 = 40 g/mol
I'm not a 100% sure if it's correct
