2.4212 X 10^ 7
How I at least figure this problem out is I take a pencil and start on the right side of the 0 and make a loop to the left for each number and count until I get to the first two numbers that are between 1-9 when reading from left to right. This is where you put the decimal point. Some teachers rather you keep the 0's there, while others prefer one to get rid of them. Anyways with that new decimal number, you multiply the decimal by ten to what ever number you counted, which was 7.
Chemical properties include reactivity with other elements of substances, toxicity, flammability, and chemical stability
just to name a few
Answer: I dunno that but u should give me brainliest

Answer:
Explanation:
The Ideal Gas Law states that PV=nRT.
Rearrange that into P/n=RT/V.
In this case, the cylinder is rigid so the volume, V, does not change.
Temperature does not change either.
Out of 450 grams of gas, 150 grams leak out. So only 450-150 = 300 grams is left.
n is number of moles which is dependent on mass:
n1/n2 = 450/300 = 3/2
P1/n1 = RT/V = P2/n2
P2 = P1/n1*n2
= 7.2/3*2
= 4.8 atmosphere
