<span>After 6 days, only 4 grams of the original amount will remain after 6
days. I have attached an image on how to calculate half-life so you can plug
your give value into the formula.

Answer:
N(CO2) = n(CO2) x Avogadros constant
n(CO2) = mass(CO2)/Molar mass(CO2) = 112/44 = 2.5454….
N(CO2) = 2.545454… x (6.02 x 10^23) = 1.5323636 x 10^24
Therefore, the number of CO2 molecules in 112 g of CO2 = 1.53 x 10^24 molecules
Explanation:
According to the law of conservation of mass, it makes a generalized observation that there will occur no change in the mass of a substance even if it undergoes a chemical reaction.
Whereas this law of conservation does not explain any phenomenon of why this conservation of mass occurs.
Therefore, the given statements are classified as follows.
A) It was developed from past observations - Ture
B) It is subject to experimentation and revision - True
C) It explains why mass is conserved - False
D) It predicts future observations - True
The answer is D. Main sequence stars
