Answer 1) a=1° = 0.01745329252 radians

Explanation : According to the conversion chart, to convert 1° this formula is used;

radians = degrees × π / 180°

while solving for, One degree which is equal 0.01745329252 radians:

1° = π/180° = 0.005555556π = 0.01745329252 rad

Answer 2) b = 1' = = 0.0002907 radians

Explanation : A minute of arc is π/10800 of radian; which is a measurement unit of angular which is equal to 1/60 of 1° degree.

So substituting the value of 1° as and on solving we get,

0.01745/60 = 0.0002907 radians.

A minute of arc is π/10800 of a radian.

Answer 3) C= 1'' = 4.8481 $X 10^{-6}$

Explanation - When calculating second of arc which is considered to be 1/60 of an arc minute, and 1/3600 of a degree;

So all these are inter-related units which can be calculated if any one value is given;

on solving we get, π/648000 (about 1/206265) of a radian = 4.8481 X $10^{-6}$

What is the volume of 3.66 x 1032 molecules of fluorine gas at STP?

kipiarov [429]

Answer:

1.36x10^10L

Explanation:

Step 1:

Determination of the mole of fluorine that contains 3.66x10^32 molecules. This is shown below:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of fluorine also contains 6.02x10^23 molecules.

Now if 1 mole of fluorine contains 6.02x10^23 molecules,

Therefore, Xmol of fluorine will contain 3.66x10^32 molecules i.e

Xmol of fluorine = 3.66x10^32/6.02x10^23

Xmol of fluorine = 6.08x10^8 moles

Step 2:

Determination of the volume occupied by 6.08x10^8 moles of fluorine.

1 mole of any gas occupy 22.4L at stp. This means that 1 mole of fluorine also occupy 22.4L at stp.

Now if 1 mole of fluorine occupies 22.4L at stp,

Then 6.08x10^8 moles of fluorine will occupy = 6.08x10^8 x 22.4 = 1.36x10^10L
