Answer:
NH3
Explanation:
Which salt is least soluble at 90 degrees Celsius
Answer:
100.52
Explanation:
from the ideal gas equation PV=nRT
for a given container filled with any ideal gas P and V remains constant.So T is also constant.R is as such a constant.
So n i.e no of moles will also be constant.
no of moles of Ar=3.224/40=0.0806
no of moles of unknown gas=0.0806
molecular wt of unknown gas=8.102/0.0806=100.52
Answer:
It's made of salt
Explanation:
The recipe has salt as an ingredient
The coefficient in a chemical formula represents the amount of each chemical present. The amount of a substance is measured in moles.
