How many moles of O2 are needed to react completely with 35.0 mol C2H2?

1 answer:

6 0

2C₂H₂ + 5O₂ ---> 4CO₂ + 2H₂O
2 mol.....5 mol

2 mol C₂H₂ --- 5 mol O₂
35 mol C₂H₂ --- X mol O₂
X = (35×5)/2
X = 87,5 mol O₂

A sample of a mineral solid weighing 28.5 g was added to a graduated cylinder filled with to a level of 20.3 mL. As a result, th

bonufazy [111]

Answer:

2.8 g/mL is the density of the mineral.

Explanation:

The mass, $m=28.5\ g$

Volume of the object = Volume of water level rose - Initial volume of water = 30.5 mL - 20.3 mL = 10.2 mL

The expression for the calculation of density is shown below as:-

$\rho=\frac{m}{V}$

$\rho=\frac{28.5\ g}{10.2 mL}=2.8\ g/mL$

<u>2.8 g/mL is the density of the mineral.</u>
