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.

Answer: longhand notation
Explanation: I just did it on Edg
Mass of MnO2 = 25 g
The reaction would be 3MnO2 + 4Al --> 3Mn(s) + 2Al2O3
Molar mass of Al = 26.982 g/mol
Molar mass of MnO2 = 54.938 + 2(15.999) = 86.936 g/mol
Calculating the moles = 25 / 86.936 = 0.2876 mol.
Mole ratio MnO2 and Al considering the equation = 3 mol of MnO : 4 mol of Al
Calculating the moles of Al = 0.2876 mol MnO2 x (4 mol of Al / 3 mol of MnO)
Number of moles of Al = 0.3834
Getting the mass in grams as asked = 0.3834 mol x 26.982 g/mol = 10.34 grams.
