P x V = n x R x T
1.00 x V = 3.50 x 0.082 x 273
1.00 x V = 78.351
V = 78.351 / 1.00
V = 78.351 L
1 mol of anything has 6.02 * 10^23 items.
4 mol has 4 times as much
C: Answer <<<<< =========
Freeze drying<span> (or lyophilization) removes water from the ice cream by lowering the </span>air pressure<span> to a point where ice sublimates from a </span>solid<span> to a </span>gas<span>. The ice cream is placed in a </span>vacuum chamber<span> and frozen until the water </span>crystallizes<span>. The air pressure is lowered, creating a partial vacuum, forcing air out of the chamber; next heat is applied, </span>sublimating<span> the ice; finally a freezing coil traps the vaporized water. This process continues for hours, resulting in a freeze-dried ice cream slice. </span>
They make science a thing. Science isn't just space and microbes etc. We need science to solve things in society, politics, and economics.
