Question

I need help with my chemistry homework. SHOW WORK

1) The density of tin (Sn) is the 5.75 g/cm^3. How many cubic decimeters (dm^3) does 17.2 kg of Sn occupy?

2) If half a liter (500 mL) of olive oil weights 425g, what is its density?

3) The density of silver is 10.5 g/cm^3. What is the mass of 0.987 dm^3 of silver ?

Answer 1

1) The gold will occupy a volume of 2.99 dm³.

`\text{Volume = 17 200 g} * \frac{\text{1 cm}^(3)}{\text{5.75 g}} = \text{2990 cm}^(3) = \textbf{2.99 dm}^(3)\\`

2) The density of the olive oil is 0.850 g/cm³.

`\text{Density} = \frac{\text{mass}}{\text{volume}} = \frac{\text{425 g}}{\text{500 cm}^(3)}= \textbf{0.850 g/cm}^(3)`

3) The mass of the silver is 10.4 kg.

`\text{Mass} = \text{987 cm}^(3) * \frac{\text{10.5 g} }{\text{1 cm}^(3 )} = \textbf{10 400 g = 10.4 kg}\\`
