Answer:
The pressure exerted by gas number 3 is 159 mmHg
Step-by-step explanation:
To answer this question, the law to Use is Dalton’s law of partial pressure
Dalton’s law of partial pressure states that for a mixture of gases which do not mix, the total pressure exerted by such gases is equal to the sum of the individual pressure.
Now for the three gases, the total pressure Pt is equal to P1 + P2 + P3
Now we have Pt = 950 mmHg, P1 = 335 mmHg and P2 = 456 mmHg
P3 = Pt-P1-P2
Plugging the values above, we have ; 950-335-456 = 159 mmHg
To solve this problem you must apply the proccedure shown below:
1. You have that Desiree wants to order 200 shirts that cost $5 and she <span> has $350 in her savings.
2. Keeping this on mind, the total cost of the shirts is:
</span>

3. Then, she must raise:
Therefore, the answer is:
