Answer:
177.1 L
Explanation:
The excersise can be solved, by the Ideal Gases Law.
P . V = n . R . T
In first step we need to determine the moles of gas:
We convert T° from, C° to K → 20°C + 273 = 293K
We convert P from mmHg to atm → 760 mmHg = 1atm
1Dm³ = 1L → 190L
We replace: 190 L . 1 atm = n . 0.082 . 293K
(190L.atm) / 0.082 . 293K = 7.91 moles.
We replace equation at STP conditions (1 atm and 273K)
V = (n . R .T) / P
V = (7.91 mol . 0.082 . 273K) / 1atm = 177.1 L
We can also make a rule of three:
At STP conditions 1 mol of gas occupies 22.4L
Then, 7.91 moles will be contained at (7.91 . 22.4) /1 = 177.1L
Answer:
New net worth to three significant figures = $80.2 billion
Dollars are given to charity = $100,250,000
Explanation:
Net worth = $77.0 billion
stock Gains = $3.20 billion
New net worth = $77.0 billion + $3.20 billion = $80.20 billion
New net worth to three significant figures = $80.2 billion
One-eighth of a percent = (1/8 x 1) / 100 = 0.00125
Dollars are given to charity = 0.00125 X $80.2 billion = $100,250,000
Or
$80,200,000,000/100 = $802,000,000
