M = moles of solute / liters of solution
2.00 M = x / 10.0 L
x = 20.0 mol
Suppose the molarity was listed as 2.0 M (two sig figs). How to display the answer? Like this:
20. mol
Hydrogen fusion is the answer. It is also known as <span>hydrogen burning. </span>
Answer:
0.371
Explanation:
number of moles = mass / Ar
= 23.8g / 32.1 + (16.0 × 2)
= 0.37129485179 = 0.371 (3 s.f).
hope it helps :)
Answer: 177600 J or 177.6kJ
Explanation:
For this problem, we need to use q = mcAT
we have m = 10000, and AT= 40. The specific heat of iron is 0.444.
So now we can plug it in: q = 10000*.444*40 = 177600 J or 177.6kJ
