Answer: A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!! :D
<u>Answer:</u> The concentration of nitrogen gas when the partial pressure is 1.086 atm above water is 
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant = ?
= molar solubility of nitrogen gas = 
= partial pressure of nitrogen gas = 0.741 atm
Putting values in above equation, we get:
Now, calculating the concentration when pressure is changed by using above equation:
= 1.086 atm
Putting values in above equation, we get:
Hence, the concentration of nitrogen gas when the partial pressure is 1.086 atm above water is
The basic building blocks are atoms

See below
Explanation:
1 year is how many seconds ?
1 year :
365 days/ yr * 24 hours / day * 60 min/ hour * 60 seconds/ min
=====
see how the 'days' 'hours' 'min' all cancel and you are left with
'seconds' / 'year' ? = 31 536 000 seconds/year
Answer:
A
Because That is the right choice
