Question

P=420HV=0.052м^3нужно найти массу

Answer 1

Формула:m=p•V следовательно
m=420•0,052=21,84грамм

Answer 2

To find the mass (m) of the substance, we can use the formula:

m = P * V

Where: P = Density of the substance V = Volume of the substance

However, I noticed that you provided the values for pressure (P) and volume (V), but the density (P) of the substance is missing. Density is required to calculate the mass. The density of a substance is typically represented by the Greek letter "ρ" (rho) and is defined as the mass (m) of the substance per unit volume (V).

If you provide the density of the substance (ρ) in units of mass per unit volume (such as kg/m^3), I'd be happy to help you calculate the mass.
