Answer:
0.75 moles
Explanation:
S2 + 2O2 = 2SO2
From the reaction above,
We see that number of moles attached to S2 is 1 and number of moles attached to SO2 is 2.
Since we want to find how many moles of S2 are needed to produce 1.50 moles of SO2 gas
The answer is gotten by proportion;
Number of moles = 1/2 × 1.5 = 0.75 moles
Answer: Climax Commuity.
Explanation: (hope it’s right! Good luck!)
Hey there :
Molar mass of NaCl = 58.44 g/mol
Number of moles :
n = mass of solute / molar mass
n = 58 / 58.44
n = 0.9924 moles of NaCl
Volume = 1.0 L
Therefore:
Molarity = number of moles / volume ( L )
Molarity = 0.9924 / 1.0
Molarity = 0.9924 M
Hope that helps!
