I belive it would be A? BUT IN NOT QUIE SURE? 0_0
Gold is an element (Au) you can identify it on a periodic table
You'll need Avogadro's number for this. NH3 has 1 Nitrogen and 2 Hydrogen. You'll multiply the molar mass of each times Avogadro's number. So:
molar mass N x 6.022x10^23 x 1 Nitrogen= total A
Molar mass H x 6.022x10^23 x 2 Hydrogen= total B
Add total A+B = your answer
I don't have a calculator or periodic table but if you plug in the numbers you'll get your answer. Hope it helps.
Answer:
I think it's A because effusion is a gas escaping from a tiny hole
Explanation:
I just finished the test and got it right :)
I believe "h" stands for hecta-, which means "one hundred."
I will convert from g to hg (divide by 100), then from mL to L (multiply by 1000).
