8 0

X=12, because when you use the constant of proportionality, which in this case is three, that’s what you multiply by 4 in the numerator side to equal 12.

Consider the following equation x= r-h/y.Solve the equation for h

Flura [38]

x= r - h/y subtract r from both sides

x-r = -h/y multiply each side by -y

-y(x-r) = h

-xy +yr = h

A mixture of gases was found to have a total pressure of 950 mmhg gas number 1 has a pressure of 335 mmhg gas number 2 has a pre

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
