Molar mass sucrose = 342.0 g/mol
V = 460 mL / 1000 = 0.46 L
Molarity = 1.10 M
mass = M * molar mass * V
mass = 1.10 * 342.0 * 0.46
mass = 173.052 g
hope this helps!
60mol O2 × 1 mol C6H12O6 / 6 moles 02 = 10 moles of Glucose
This is a relatively easy half-life problem.
Whenever a half-life has expired, one half of the radioactive isotope will no longer be present.
When 2 half-lives have occurred, then one quarter of the isotope remains.
Therefore, the strontium - 90 will be at a safe level in 54 years.
Hey there!
I attached a screenshot of my chemistry notes from this year on equilibrium constants in particular. Feel free to reference this in the future if you wish.
Based on the information in my attachment, you could construct your constant like this:
I don't think it matters which order your reactants or products are in as long as you have them on the top and bottom where they need to be, so your answer will be B.
Hope this helped you out! :-)
