You go fishing and obtain some lead weights for your trip. Since you are the smartest chemistry student
in the land, you know that lead's density is 11.34 g/mL. If there are 50 weights in a 250. mL box, what is
the mass of each weight?

Pls show work if u can!

Answer:

56.7g

Explanation:

Density = mass/volume

According to this question, some lead (Pb) of certain weights was obtained on a fishing trip. The density of lead is given as 11.34g/mL. If the 50 weights are placed in a 250. mL box, the mass of the lead are as follows:

Density = mass ÷ volume

11.34g/mL = mass/250mL

mass = 250 × 11.34

mass = 2835g

Since the 50 weight of lead weighs 2835g, then the mass of each weight is calculated as follows:

= 2835/50

= 56.7g
