Solar Energy is the answer
The result of acid on rain on buildings and bridges would be decay and rotting, the chipping and loss of cement.
Molar C6H12O6 = 180.15 g/mol
180.15 g -------------- 6.02x10²³ molecules
?? g ------------------- 3.5x10²² molecules
( 3.5x10²²) x 180.15 / 6.02x10²³ =
=> 10.47 g
B.
its the only one with ozone in the reaction O₃
Answer:
0.295 mol/L
Explanation:
Given data:
Volume of solution = 3.25 L
Mass of BaBr₂ = 285 g
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of solute:
Number of moles = mass/ molar mass
Molar mass of BaBr₂ = 297.1 g/mol
Number of moles = 285 g/ 297.1 g/mol
Number of moles= 0.959 mol
Molarity:
M = 0.959 mol / 3.25 L
M = 0.295 mol/L
