Answer:
44.8 grams
Explanation:
The density exists as a ratio comparing the mass of a piece of copper per 1 cm³. Since you have been given a new volume, you can set up a proportion to find the new mass.
<----- Proportion
<----- Cross-multiply
<----- Divide both sides by 1.00

I belive it is the range hope it helped! :)
Explanation:
The correct mole ratio of K₃PO₃ and KNO₂ in the chemical reaction is 1 : 3
<h3>Balanced equation</h3>
3Mg(NO₂)₂ (aq) + 2K₃PO₃ (aq) -> Mg₃(PO₃)₂(aq) + 6KNO₂(aq)
from the balance equation,
- The number of mole of K₃PO₃ = 2 moles
- The number of mole of KNO₂ = 6 moles
<h3>How to determine the mole ratio of K₃PO₃ and KNO₂</h3>
- Number of mole of K₃PO₃ = 2 moles
- Number of mole of KNO₂ = 6 moles
- Mole ratio of K₃PO₃ and KNO₂ =?
Mole ratio = mole of K₃PO₃ / mole of KNO₂
Mole ratio of K₃PO₃ and KNO₂ = 2 / 6
Mole ratio of K₃PO₃ and KNO₂ = 1 : 3
