Which of these measurements is expressed as three significant figures?
C. 4.20 g
To find out the pressure in atm. You must divide 385 by 760. So pressure in atmospheres equals 385/760.
A. 1.01 is the right answer
Since
The formula is Pv= nRT
P=1 atm
V= 22.4 L
N= x
r= 0.0821
t = 273 k (bc it’s standard temperature)
So (1)(22.4)=(x)(0.0821)(273)
X= 1.001
