Social interactions help lower the risk of Alzheimer diseases by stimulating the brain. Many studies show that if you use your brain more you have a lower chance of getting Alzheimer's.
Given which are missing in your question:
the flask is filled with 1.45 g of argon at 25 C°
So according to this formula (Partial pressure):
PV= nRT
first, we need n, and we can get by substitution by:
n = 1.45/mass weight of argon
= 1.45 / 39.948 = 0.0363 mol of Ar
we have R constant = 0.0821
and T in kelvin = 25 + 273 = 298
and V = 1 L
∴ P * 1 = 0.0363* 0.0821 * 298 = 0.888 atm
Answer:
Required number is the vertical coordinate of the intersection point of a line at 60°C with the graph of the KNO₃.
