number 2 is community sense lions ain't everywhere I not sure tho
<h3>
Answer:</h3>
2.41 g NaCl
<h3>
Explanation:</h3>
We are given the;
Molarity of NaCl = 0.150 M
Volume of the solution = 275.0 mL
We are required to calculate the mass of NaCl solute;
<h3>Step 1: Number of moles of NaCl solute </h3>
Moles are calculated by;
Moles = Molarity × Volume
Therefore;
Number of moles of NaCl = 0.150 M × 0.275 L
= 0.04125 moles
<h3>Step 2: Mass of NaCl solute </h3>
Mass of the compound is given by multiplying the number of moles by the molar mass of the compound.
Molar mass of NaCl = 58.44 g/mol
Therefore;
Mass of NaCl = 0.04125 moles × 58.44 g/mol
= 2.41 g
Thus, the mass of NaCl solute is 2.41 g
