Answer:
0.2886 Kmoles
Explanation:
Number of moles is calculated by dividing mass of element/molecular mass of element
Mass of Carbon Di oxide = 5000 g or 5 kg
Molecular mass of CO2 = 12 + 16×2 = 44 g
No of moles = 5000/44 = 113.6 moles = 0.1136 Kmoles
Mass of argon = 7Kg or 7000 kg
Molecular mass of Argon(Ar) = 40g
No of moles = 7000/40 = 175 moles = 0.175 Kmoles
Total Kmoles = 0.175+0.1136=0.2886 Kmoles

I HOPE ITS RIGHT IF NOT THEN SORRY</h3>
HAVE A GREAT DAY :)
Answer: I believe farther. Correct me if I am wrong
Explanation:
Answer:
I will answer this in English.
He has 45 years.
a year has 365 days.
a day has 24 hours.
So he has:
45*365*24 hours = 394,200 hours.
His mass is 78 kg,
And we know that 1 slug = 1lbf*ft/s^2
Then, the first step is transform the 78 kg into lbf.
1kg = 2.2 lbf.
then 78kg = 78*2.2 lbf = 171.6lbf.
Now, the weight is m*g, where m is the mass and g is the gravitational acceleration, in this case the gravitational acceleration in ft/s^2 is:
g = 32.2 ft/s^2
Then the weight in slugs is:
W = 32.2ft/s^2*171.6lbf = 5,525.5 slugs
