Question

V=18.75л P=? рк=0.8г/см

Answer 1

надеюсь ,что под Р подразумевается сила F

P=mg       Po=0.8r/cm=0.08kg/m

m=Po*V=0.08*18.75=1.5

P=mg=1.5*10(т к ускорение свободного падение равно 10)=15H

Ответ:P=15H

Answer 2

To calculate the pressure (P) of a gas, we can use the ideal gas law, which is given by the formula:

$PV = nRT$

where: P = pressure of the gas (in atmospheres, Pa, kPa, etc.) V = volume of the gas (in liters, m³, etc.) n = number of moles of gas R = ideal gas constant (varies based on units; commonly used value is 0.0821 L·atm/(mol·K)) T = temperature of the gas (in Kelvin)

However, we need additional information to solve this problem. Specifically, we need to know either the number of moles of gas (n) or the temperature (T). Without that information, we cannot find the pressure.

If you can provide either the number of moles or the temperature, I'll be able to help you calculate the pressure.
