The molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated by dividing the number of moles of the solute by the volume of the solution as follows:
Molarity = no of moles ÷ volume
According to this question, a solution has 26 moles of NaCl in 2. 7 l of water. The molarity is as follows:
Molarity = 26mol ÷ 2.7L
Molarity = 9.6M.
Therefore, the molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.

4) definite shape and definite volume
hydrogen and helium and the most abundant elements in a nebula.
Answer is 334.35 g.
<em>Explanation:</em>
n = m/M
Where n is the number of moles of given substance (mol), m is the mass (g) and M is the molar mass of the substance (g/mol).
n = 3.99 mol
m = ?
M = 83.798 g/mol
By applying the formula,
3.99 mol = m / <span>83.798 g/mol
</span> m = 3.99 mol x <span>83.798 g/mol
</span> m = 334.35 g
Answer:
D) Rate = K [NO2][Cl2]
Explanation:
2 NO2 + Cl2 → 2 NO2Cl (overall reaction)
NO2 + Cl2 → NO2Cl + Cl (slow)
NO2 + Cl → NO2Cl (fast)
The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
Rate of reaction is typically given as;
Rate = K [Reactants]
In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.
Rate = K [NO2][Cl2]
