Answer:
![y-4/x^{2}](https://tex.z-dn.net/?f=y-4%2Fx%5E%7B2%7D)
Step-by-step explanation:
10% = 10g/100ml. Ergo, 15ml/100ml (10g) = 1500mg of KCL
.9% NACL = 9g/1000mL, Ergo = 9000mg NaCl
Now we have to figure out how many mEqs of each salt we have.
MW of NaCl = 58.5
MW of KCl = 74.5
So, in moles, we have:
1500 KCl / 74.5 = 20.13 mmol KCl
9000 NaCl / 58.5 = 153.85mmol NaCl
Because the valence of both ions is one, as an example, it would be both 20.13 mEq of Cl- and K+ from 20.13 mmoles of KCL.
So, just add the two together, 20.13 + 153.85 = 174-ish.
Answer:
22.5 cm²
Step-by-step explanation:
La fórmula para el volumen de un prisma con una base hexagonal = Área de la base × Altura
De la pregunta anterior
Área de la base =?
Altura = 3 cm
Volumen = 67.5 cm³
Área de la base = Volumen ÷ Altura
Área de la base = 67.5 cm³ ÷ 3cm
= 22.5 cm²
Por lo tanto, el área si es base = 22.5 cm²
