How many moles are contained in a 4.67-l sample of gas at 30 c and 199 kpa?
valentina_108 [34]

Using ideal gas equation,

PV=nRT

P=199 kpa

V=4.67 L

T=30+273K= 303K

n= number of moles of gas

R=8.321 L·kPa·K-1·mol-1

So using ideal gas equation,

n=PV/RT

=199*4.67/8.321*303\

=0.37 mol

At what temperature are ice and liquid water in equilibrium with each other? What is this temperature is called?
melomori [17]
The single combination of pressure and temperature at which liquid water, solid ice, and water vapor can coexist in a stable equilibrium occurs at approximately 273.1575 K (0.0075 °C; 32.0135 °F) and a partial vapor pressure of 611.657 pascals (6.11657 mbar; 0.00603659 atm).[4][5] At that point, it is possible to change all of the substance to ice, water, or vapor by making arbitrarily small changes in pressure and temperature. And the temperature is called Triple point

Answer:

The median would be 6700

Explanation:

Arrange data values from lowest to highest value

The median is the data value in the middle of the set

.

Ordering a data set x1 ≤ x2 ≤ x3 ≤ ... ≤ xn from lowest to highest value, the median x˜ is the data point separating the upper half of the data values from the lower half.

If the size of the data set n is odd the median is the value at position p where

Formula for the median

p=n+12

x˜=xp

If n is even the median is the average of the values at positions p and p + 1 where

p=n2

x˜=xp+xp+12

If there are 2 data values in the middle the median is the mean of those 2 values.
