Answer:
The number of molecules in a mole (known as Avogadro's constant) is defined such that the mass of one mole of a substance, expressed in grams, is equal to the mean molecular mass of the substance. The molecular mass of CO2 = 12+2x16 = 44, so the mass of a mole of CO2 is approximalty 44 grams
Explanation:
Answer:
Explanation:
Silver chloride precipitates out because it has a low value of Ksp.
Answer:
MgCl2-> Mg+Cl
mass 5.00g Mass=1.263g
RFM Mg=24+35.5 ×2= 95 RFM= 24
moles= 5.00÷ 95= 0.0526 Moles=0.0526
Explanation:
mas of Mg= 1.263 grams
Answer:
Follows are the solution to these question:
Explanation:
Given equation:
In this equation:
gives 
so,
gives= 
similarly:
gives
So, 
gives = 
Its limited reagent is =
The amount of 
molecules were formed = 4.
and the amount of 
excess molecules are= 1
Second choice is electron cloud and first is a discrete amount thst is fixed
