A saline solution contains 1.3% NaCl by mass. How much NaCl is present in 83.2g of this solution?

To find the amount of NaCl present in the given saline solution, we need to calculate the mass of NaCl in 83.2g of the solution.

Step 1: Convert the percentage to a decimal.
1.3% = 1.3/100 = 0.013.

Step 2: Calculate the mass of NaCl.
Mass of NaCl = (0.013) * (83.2g) = 1.0796g.

Therefore, there is approximately 1.08g of NaCl present in 83.2g of the solution.
