Answer:
It is important to collect all data first, or else your guesses could purely be the opposite of the right answer. If you make inferences of what might happen, your guesses may be purely fictional, and totally off-topic. During experiments, this step is important.
Answer:
58.944 g
Explanation:
From the question given above, the following data were:
Mole of SO2 = 0.9210 mole
Mass of SO2 =?
Next, we shall determine the molar mass of SO2. This can be obtained by adding the molar mass of sulphur and oxygen together as illustrated below:
Molar mass of SO2 = 32 + (2 × 16)
= 32 + 32 = 64 g/mol
Finally, we shall determine the mass of 0.9210 mole of SO2 as follow:
Mole of SO2 = 0.9210 mole
Molar mass of SO2 = 64 g/mol
Mass of SO2 =?
Mole = mass /Molar mass
0.9210 = mass of SO2 / 64
Cross multiply
Mass of SO2 = 0.9210 × 64
Mass of SO2 = 58.944 g
Thus, the mass of SO2 is 58.944 g.
