So number molecules in the sample = moles x 6.022x10^23 molecules/mole
= 0.450 mol x 6.022x10^23
= 2.71x10^23 molecules
The relative ratio, uav : ump : urms of a gas at a given temperature is 56 / 22 : 2 : 3.
<h3>What is temperature?</h3>
Temperature is the measurement of hotness or coldness of a body. It shows the direction of flow of heat.
The relative rate (RR), also known as a rate ratio, is the ratio of the disease or death incidence rate in the exposed group to the disease or death incidence rate in the unexposed group.
Thus, the relative ratio, uav : ump : urms of a gas at a given temperature is 56 / 22 : 2 : 3.

Answer:
C.
Explanation:
Iron is most likely to form a precipitation reaction.
Answer:
589 torr or mmHg.
Explanation:
We know that 1 atmospheric pressure is equal to 760 torr or 760 mmHg so calculate 0.775 atm pressure in term of mmHg and torr. We perform the following steps which is
1 atm -------- 760 torr or mmHg
0.775 atm ------- X
By cross multiplication we get
X = 760 x 0.775
X = 589 torr or mmHg
So we can conclude that if 0.775 atm is equals to 589 torr.
