Molar mass of butane:-

  • 4(12)+10=58u

Moles of Butane:-

  • 100/58=1.7mol

#16

  • 2mols of Butane produce 8mol CO_2
  • 1mol of butane produces 4mol CO_2

Moles of CO_2

  • 4(1.7)=6.8mol

Mass of CO_2:-

  • 44(6.8)=299.2g

#17

  • 2mols of butane need 13mol O_2
  • 1mol of butane needs 6.5mol O_2

Moles of O_2

  • 6.5(1.7)=11.05mol

Mass of O_2

  • 11.05(32)=353.6g

The ion p3− has _____ protons and _____ electrons. enter your answers as integers separated by a comma.'
katrin2010 [14]

The symbol P is for phosphorus having atomic number 15. That means it has 15 protons and 15 electrons in its neutral state.

The given symbol P^{3-} has a -3 charge that means it has gained 3 electrons so, the number of electrons in the P^{3-} is: 15+3 = 18. The number of protons will remain same that is the number of protons = 15.

So, the ion P^{3-} has 15 protons and 18 electrons that gives 15-18=-3 charge on the P^{3-} ion.

So, the answer is 15 , 18.
