Final answer:

To find the percent by mass of HCl in the tile cleanser with 135 g HCl and 775 g water, you divide the mass of HCl by the total mass then multiply by 100%, yielding about 14.84% HCl.

Step-by-step explanation:

To calculate the percent by mass of HCl in a tile cleanser that contains 135 g of HCl and 775 g of water, you would use the formula for mass percentage. The formula is:

Mass percent of a component = (mass of the component / total mass of the solution) × 100%

Applying the formula:

Mass percent of HCl = (135 g / (135 g + 775 g)) × 100%

Calculating this gives:

Mass percent of HCl = (135 g / 910 g) × 100%

Mass percent of HCl ≈ 14.84%

Therefore, the percent by mass of HCl in the cleanser is approximately 14.84%.

The answer is 1/31 cleaner because there are 31 total parts and only one is cleaner
