6 0

Answer: 36 moles oxygen

Step-by-step explanation:

C10H8 + 12O2 ====》 10CO2 + 4H2O

From the equation of the reaction,

1 mole of napth requires 12 moles of O2

3 moles of napth would require x moles O2

X = (3 * 12) / 1

X = 36 moles of oxygen.

Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen

Wheel world sold 875 cars last year if the sales this year are 120% of sales last year how many cars will they sell this year
inn [45]

okay so first you wanna turn that 120% into a decimal and the decimal form of that would be 1.2 or 1.20

Secondly you want to multiply 875 by the 1.2

875*1.2 = 1050

So if they sell 120% of last years sales they will sell 1050 cars this year.

Hope this helped :)
