If 14 grams of hydrogen reacted with 24.7 grams of oxygen 27.7875 grams of water will be formed.

Explanation:

2H2+O2----------->2H2O.

  • From the above equation, we can say that 4g of Hydrogen will react with 32 g of oxygen.
  • In this question, Hydrogen is in excess amount.
  • 32 g of Oxygen will react with = 4 g of H2.
  • Therefore 24.7g of Oxygen will react with =24.7x4/32= 3.0875 g H2.  
  • The remaining 10.9125g of H2 will be left unreacted.
  • Therefore the amount of water formed=(24.7+3.0875)=27.7875 g

3. Calculate the volume, in mL, of 100.0 g of alcohol, if the density is 0.79 g/mL.
Naya [18.7K]

Answer:

The answer is

<h2>126.58 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

<h3>volume =  \frac{mass}{density}</h3>

From the question

mass of alcohol = 100 g

density = 0.79 g/mL

The volume is

volume =  \frac{100}{0.79}  \\  = 126.58227848...

We have the final answer as

<h3>126.58 mL</h3>

Hope this helps you
