Answer:
8 cm3
Explanation:
The volume of this irregular solid will calculated as the difference between the final volume and the initial volume;
The final volume of the water and the solid is 25 ml
The initial volume of the water alone was 17 ml
The volume of the irregular solid is thus approximately;
25 - 17 = 8 ml
We then use the conversion;
1 cm3 = 1 mL
Thus the volume of the solid is 8 cm3
Hey...
Use the molarity formula
M=moles/L and then convert to grams
0.07268*0.15=moles
<span>0.010902 mol
</span>Pb(NO3)2
1 mole=331.22g
0.010902 moles=
3.61 g
C. Adding air would add to volume. Since it's by volume not weight they'd want more volume because more volume means more money
Question
What mass of Al₂O₃ form is produced if 25.00 g of aluminum (al) is reacted completely?, knowing the molar mass of Al₂O₃ is 102 g/mol?
Atomic mass of Al =27 and O = 16
The molar mass of Al₂O₃ = 102.
Mass of aluminium in 102 g of Al₂O₃ = 54 g
54 g Al => 102 g Al₂O₃
25g Al => x g Al₂O₃
x = 25*102/54 = 47.2 g Al₂O₃
