How many molecules do you have in 64 g of CO2?

8.757 x 10^23 molecules

Explanation:

Use Avogadro's number of  6.022 × 10 ^23  molecules per mole.

64g CO2/44.01 g/mol = 1.454 moles of CO2

1.454 x  6.022 × 10 ^23 =

8.757 x 10^23 molecules

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.
