Answer:
No it does not space does not have oxygen and air is caused by oxygen
hey but this was a really interesting question to ask tho
Explanation:
Answer : The amount of formaldehyde permissible are, 
Explanation : Given,
Density of air =

First we have to calculate the mass of air.



Now we have to calculate the amount of formaldehyde.
Permissible exposure level of formaldehyde = 0.75 ppm = 
Amount of formaldehyde in 7.2 g of formaldehyde = 
Amount of formaldehyde in 7.2 g of formaldehyde = 
Thus, the amount of formaldehyde permissible are, 
Answer:
The answer to your question is below
Explanation:
1.-
a) Look for the mass number of Gold in the periodic table
Mass number = 197 g
Use proportions to answer this question
197 g of gold ------------- 6.023 x 10 ²³ atoms
4.64 g of gold ---------- x
x = (4.64 x 6.023 x 10²³) / 197
x = 1.42 x 10²² atoms
2.- mass of 4.12 x 10²⁴ molecules of glucose
Molecular mass = (6 x 12) + (12 X 1) + (6 x 16)
= 72 + 12 + 96
= 180 g
180 g of glucose ------------------- 6.023 x 10 ²³ molecules
x ------------------- 4.12 x 10 ²⁴ molecules
x = (4.12 x 10²⁴ x 180) / 6.023 x 10²³
x = 1231.3 g of glucose
