The mass of the alloy, consisting of tin and lead, is 600 g. The alloy contains 68% tin. Find the mass of lead.

First, let’s find the percentage of lead in the alloy:

100 – 68 = 32 (%) – the percentage of lead in the alloy.

Now let’s find how much 1% of the alloy weighs. To do this, divide the total weight of the alloy by 100:

600/100 = 6 (g) – weight of 1% alloy.

Next, you can find the mass of lead in the alloy by multiplying the weight of 1% of the alloy by the percentage of lead in the alloy:

6 * 32 = 192 (g)

Answer: The alloy has 192 grams of lead
