What is the mass of 0.9210 moles of sulfur dioxide gas (SO2)?

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.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
