Answer:
159.3 grams Al
Explanation:
1 Mol of Al = 27 grams, so:
5.9 Mol Al (27g/1mol) = 159.3 grams Al
The Mol gets canceled out, leaving the unit of grams.
Answer:
833.12g
Explanation:
Use the mole=mass/mr equation (rearrange this to find mass)
Mr= 164
So, 5.08 x 164 = 833.12g
Answer:
Speed = frequency x wavelength 50 cm/s = Freq x 10cm
Explanation:
>(7.5 * 10^23) molecules / (6.022 * 10^23 molecules / mole) = 1.2 mol H2SO4 Third multiply moles H2SO4 by molar mass of H2SO4.<
