What is the mass of 0.9210 moles of sulfur dioxide gas (SO2)?
Paul [167]

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.

Cold solvents are preferred for recrystallization because Group of answer choices Hot solvents catch fire easily to prevent diss
aev [14]

Crystals impurities are expected to have high solubility in cold solvents. Hence, option C is correct.

<h3>What is a cold solvent?</h3>

Cold solvent cleaning is a process used to remove grease, wax and other impurities from metal and other parts.

The process is also called degreasing. Cold solvents are sprayed onto the dirty part and it is brushed clean.

Once the filtration process is done the collected crystals should be washed with a little more ice-cold solvent to remove final soluble impurities which would otherwise be left on the surface of the crystals.

Hence, option C is correct.

A gas occupies 900.0 mL at a temperature of 27.0 . What is the volume at 132.0 °C?
Ronch [10]
V₁ = 900.0 mL

T₁ = 27.0ºC + 273 = 300 K

V₂ = ?

T₂ = 132.0 + 273 = 405 K

V₁ / T₁ = V₂ / T₂

900.0 / 300 = V₂ / 405

300 x V₂ = 405 x 900.0

300 x V₂ = 364500

V₂ = 364500 / 300

V₂ = 1215 mL

hope this helps!
