Answer:
The correct answer is - 66g.
Explanation:
Given:
molecules of CO2 = 9.03 x 10^23
We know:
1 mole of any substance = 6.02x10^23 molecules. (Avogadro's number)
M (CO2) = 12 + (2x16) = 12 + 32 = 44g
Solution:
The mass of CO2 with 9.03x10^23 molecules would be:
44g of CO2 = 6.02x10^23 molecules.
So, the mass in grams of CO2 (X) = 9.03x10^23 molecules
Xg of CO2 = (44x9.03x10^23)/6.02x10^23 = 66g
Thus, the correct answer would be - 66gm.
Answer:
The answer is
<h2>0.307 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of box is 345 g
volume = 1125 cm³
The density of the object is
We have the final answer as
<h3>0.307 g/cm³</h3>

Answer:
A, D,E
Explanation:
I think thats right. Cuz losing electrons makes you cation, gaining electron by a neutral atom makes you negative, and giving up electrons is synonymous to acting like a "metal"
I'm pretty sure it would feel like magic, You could definitely float when you jump
