How many grams of oxygen are required to burn 4.8 mol of butane?
The balanced equation for the reaction is 2 C4H10 + 13 O2 -> 8 CO2 + 10 H2O. This shows that 13 moles of diatomic oxygen are required to burn 2 moles of butane. By proportionality, (4.8/2)13 or 31.2 moles of oxygen are required to burn 4.8 moles of butane. This corresponds to 31.2(32) or 1.0 X 103 grams of oxygen.
What element has a mass number of 103 and electrons of 45?

How many molecules of ammonia are present in one milli mole of ammonia?
One mole=1000 Milli moles One mole=6.022 x 1023 molecules of the substance Therefore, one Milli mole of ammonia has 6.022 x 1023 /103 = 6.022 x 1020 molecules of ammonia.
What is 33 degrees Celsius to Fahrenheit?
It's easy to convert from Celsius to Fahrenheit by yourself. Tf = (9/5)*Tc+32, where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. 33 C is 91.4 F.
How many milliliters of hydrochloric acid are needed to react with 56.5g of zinc sulfide?
ZnS + 2 HCl --> Zn2+ + 2Cl- + (H2S)gasBe careful!Almost 13 Litre of very toxic (or poisonous and stinky) hydrogen sulfide gas (H2S) will be produced. Only to be performed in absolutely approved and controlled laboratory conditions with a alkaline gas scrubber! Remember: H2S is already poisonous when you can't even smell it.(Its MAC-dose concentration is lower than its odour threshold)Stoiciometric Calculus:56.5 (g ZnS) / 97.474 (g/mol ZnS) = 0.5796 mol ZnS == 0.5796 (mol ZnS) * (2 mol HCl / mol ZnS) = 1.16 mol HClHow many Millilitres you'll need depends on the concentration HCl (in mol/L = mmol/ml ):1.16*103 (mmol HCl) / (concentration HCl) = (1.16*103 / c) ml HCl.This is a single disposition reaction.
