What volume of solution is needed to prepare a 0.50M solution of sodium hydroxide using 2.0 g of solute? Show your work

Chemistry
1 answer:
Aleks04 [339]3 years ago
6 0

Answer:

0.10 L

Explanation:

First we <u>convert the 2.0 grams of solute</u> (meaning <em>sodium hydroxide</em>)<u> into moles</u>, using its <em>molar mass</em>:

  • 2.0 g ÷ 40 g/mol = 0.05 mol NaOH

Then we can <u>calculate the required volume of solution</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • liters = moles / molarity
  • 0.05 mol / 0.50 M = 0.10 L

How many molecules of ammonia are formed in the following equation: N2+3H2→2NH3
Katena32 [7]

Answer:

  • <u>two molecules of ammonia are formed by the reaction of one nitrogen and three hydrogen molecules.</u>

Explanation:

The  balanced chemical equation provides information on:

  • <u>Reactants</u>: those are the compounds that appear of the left side of the equation, each with its chemical formula.

  • <u>Products</u>: those are the compounds that appear on the right side of the equation, again, each with its chemical formula.

  • <u>Ratio</u>: the coefficients of each compound (the number to the left of the chemical formula) represent the ratio of the number of molecules that react and are formed.

In the given equation you have:

  • Equation: N₂ + 3H₂ → 2NH₃

  • The coefficients are 1 for nitrogen, 3 for hydrogen, and 2 for ammonia. Hence, 2 molecules of ammonia are formed by the reaction of 1 molecule of nitrogen and 3 molecules of hydrogen.
