How many grams would you add to a gallon of water to make a 7% sodium hydroxide solution?

You would use a “percent by weight/volume” calculation, since you’re dissolving a compound by weight into a fixed volume of solution. The units must all be in the same system of measurement. In your example, to get a 7% solution you would first convert the gallon volume to milliliters, which is 3785.41 ml. Multiply that by .07 to get the the weight of NaOH in grams to add to the water. This works because 1mL water equals 1 gram.

Would this product be good for clearing a clogged sink/tub drain?

You certainly could, but it would be a hugely expensive waste to use laboratory-grade sodium hydroxide, which is costing nearly $4 per ounce, when you get ordinary “pure” (but no lab-grade) for less than fifty cents an ounce. That’s an 800% premium, and I’ll wager that the lab-grade pellets are not the best form for a drain anyway. The smaller tiny beads in drain-cleaner form will flow through a drain more easily. Amazon sells lots of the “pure” drain cleaner. Buy that instead.

Lab-grade sodium hydroxide pellet, 100g: how many pellets are in a 100 g bottle?

The pellets are cherry-pit-sized, so maybe 1000. I’ll post a review with a picture.

Lab-grade sodium hydroxide pellet, 100g: does this mean that one pellet weighs 100g?

It means the total weight of the pellets inside the bottle is 100g. -hBARSCI
