Answer:
1,816 L
Explanation:
Molar concentration or molarity is a way to express the concentration of a chemical in terms of moles of substances per liter of solution.
To obtain the liters of this solution you must convert moles/L to g/L with formula weight (FW), thus:
0,1107 mol of KCl / L × (74,6 g / mol) = 8,258 g of KCl / L.
It means that in one liter you have 8,258 g of KCl. Thus, 15,00 g of KCl are contained in:
15,00 g × (1 L / 8,258 g) = 1,816 L
I hope it helps!
Answer: 1,762.97 ft² ≈ 1,763 ft²
Explanation:
1) Conversion factor:
1 ft = 0.305m ⇒
1 = 1 ft / 0.305m ⇒
´[1]² = [1 ft / 0.305m]² ⇒
1 = 1 ft² / (0.305m)² ⇒
1 = 1 ft² / 0.093025 m²
2) 164 m²
164 m² × 1 ft² / 0.093025 m² = 1,762.97 ft² ≈ 1,763 ft²
You need to find number of moles of methane and oxygen. then make ratios
