Answer:

38.6%

Explanation:

Molar mass of KNO3 is

=39+14+(16*3)

=53+48

=101 g/mol

Now

Percentage composition of potassium in KNO3 is=(atomic mass of K*no. of atoms)/molar mass of KNO3 *100%

%age composition of K= (39*1)/101 *100%

=0.386*100%

=38.6%

Explain why you hear a “whoosh” sound when you open a can containing a carbonated drink. Which gas law applies?
Lana71 [14]

Carbonated drinks have the air under pressure so that carbon bubbles are forced into the drink, keeping it carbonated. So when you open a can, the air under pressure in the can comes out of the can at a high speed, making a "whooshing" sound. The gas law that applies to this concept is the Boyle's Law (PV=k or P1V1=P2V2).
