Answer:
R=0·083 J/mol·K
Explanation:
Ideal gas equation is
<h3>P×V = n×R×T</h3>where,
P is the pressure of the gas
V is the volume of the gas
n is the number of moles of the gas
R is ideal gas constant
T is the temperature of the gas in Kelvin
In case of given problem
Temperature of the gas = 273+2·00=275·00K
P=259,392·00× atm
(259,392·00× )×8·8 = 1×R×275·00
∴R=0·0830 J/mol·K
But according to the rules of significant figures the value of R must be with least precision of all the values of the other parameters from which the value of R is calculated
Here the least precision is in the volume as it contains only 2 significant digits
∴ Value of R must contain 2 significant digits
∴ R=0·083 J/mol·K
Answer:- There are moles.
Solution:- It is a unit conversion problem where we are asked to convert mg of aspartame to moles. Aspartame is and it's molar mass is 294.31 grams per mole.
mg are converted to grams and then the grams are converted to moles as:
= moles of aspartame
So, there would be moles of aspartame in 1.00 mg of it.
