Question

Масса пустой пол-литровой бутылки равна 400 г. Каков ее наружный объем?

Answer 1

Плотность стекла примерно 2500 кг/м³ 
Объем стекла массой 0,4кг = 0,4/2500=0,00016м³ =0,16дм³ 
Наружный объем бутылки = объем стекла + поллитра пустоты = 0,16дм³ + 0,5дм³ = 0,66дм³ (660 мл)

Answer 2

Calculating the External Volume of the Bottle

To calculate the external volume of the bottle, we can use the formula for density, which is mass divided by volume (ρ = m/V). Given that the empty bottle has a mass of 400 grams, we can use this information to calculate its external volume.

Using the formula ρ = m/V, where ρ is the density, m is the mass, and V is the volume, we can rearrange the formula to solve for V:

V = m/ρ

Substituting the given mass of the empty bottle (m = 400 g) into the formula, we can calculate the external volume of the bottle.

Calculation

V = m/ρ V = 400 g/ρ

Now, we need to find the density (ρ) of the material the bottle is made of. Unfortunately, the search results did not provide specific information about the density of the material, so we are unable to calculate the external volume of the bottle based on the given information.

If you have any additional information about the material of the bottle, such as its density, please feel free to provide it, and I can help you calculate the external volume using that information.
