Answer:

55 g

Explanation:

First, we have to look for the solubility of KNO₃ at 60°C, considering that the solubility is the maximum amount of solute that can be dissolved in 100 grams of solvent, that is, the concentration of a saturated solution.

The solubility of KNO₃ at 60°C is 110.0 g of KNO₃ per 100 g of water. The mass of KNO₃ that must be dissolved in 50 g of water to make a saturated solution is:

50 g H₂O × (110.0 g KNO₃/100 g H₂O) = 55 g KNO₃

If 3.0 moles of hydrogen react, how many grams of nitrogen will be used? Round your answer to the nearest whole number. N2 + 3H2

Iteru [2.4K]

Answer:

28g

Explanation:

Given parameters:

Number of moles of hydrogen = 3moles

Unknown:

Mass of nitrogen used = ?

Solution:

To solve this problem, let us establish the balanced reaction equation first;

N₂ + 3H₂ → 2NH₃

From the balanced reaction equation;

3 mole of H₂ will combine with 1 mole of N₂

Now,

Mass of Nitrogen = number of moles x molar mass

Molar mass of N₂ = 2(14) = 28g/mol

Mass of Nitrogen = 1 mole x 28g/mole = 28g

timofeeve [1]

<u>Answer:</u> The expression for equilibrium constant in terms of concentration is $K_c=[CO_2]$

<u>Explanation:</u>

Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by $K_{c}$
