Answer:
273 mL.
Explanation:
From the question given above, the following data were obtained:
Molarity of HBr = 0.220 M
Mole of HBr = 0.060 mole
Volume =?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole /Volume
With the above formula, we can obtain the volume required as illustrated below:
Molarity of HBr = 0.220 M
Mole of HBr = 0.060 mole
Volume =?
Molarity = mole /Volume
0.220 = 0.060 / Volume
Cross multiply
0.220 × Volume = 0.060
Divide both side by 0.220
Volume = 0.060 / 0.220
Volume = 0.273 L
Finally, we shall convert 0.273 L to millilitres (mL). This can be obtained as follow:
1 L = 1000 mL
Therefore,
0.273 L = 0.273 L × 1000 mL / 1 L
0.273 L = 273 mL
Thus, 0.273 L is equivalent to 273 mL.
From the calculations made above, 273 mL of HBr is required.
