Answer the following questions based on zinc. 1. what mass of copper would have a volume of 35.15 cm3? 2. what volume would 71.45g of copper shot occupy? 3. if 50.0 cm3 of one type of metal has a mass of 352 g, is this metal copper? explain.

1. 315 g; 2. 7.97 cm³; 3. The metal is not copper.

1. Mass of copper

The density of copper is 8.96 g/cm³.

Mass = 35.15 cm³ × (8.96 g/1 cm³) = 315 g

2. Volume of copper

Volume = 71.45 g × (1 cm³/8.96 g) = 7.97 cm³

3. Identification of metal

Density = mass/volume = 352 g/50.0 cm³ = 7.04 gcm³

The metal is not copper because its density is much% less than that of copper.

b) mutualism

hope this : )

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
