so basically what i was thinking of was they sold them in the spring
Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.
lowkey hope this helped you, good luck whatever you need it for Imaooo
C. 4 because 4 is a perfect square, as well as x^2 and 4x
I hope that helps!
hello
so this equation is written in point slope form: 
we can solve for y to get the equation into slope intercept form: y=mx+b
y+1=4/3x
subtract 1 from both sides
y=4/3x-1
slope: 4/3
y-intercept: -1
hope this helps
have a nice day :)
