7) What is the density of sulfur dioxide, SO2, at
STP?

The density of SO₂ is  2.858 g/L.

Explanation:

Given data:

Density of sulfur dioxide = ?

Given temperature = standard = 273 K

Given pressure = standard = 1 atm

Solution:

Formula used:

PM = dRT

P = pressure

M = molar mass

d = density

R = ideal gas constant

T = temperature

No we will put the values in formula

1 atm × 64.066 g/mol = d× 0.0821 atm.L/mol.K× 273 K

d =64.066 atm.g/mol  /22.4133atm.L/mol

d = 2.858 g/L

The density of SO₂ is  2.858 g/L.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
