The mass decay rate is of the form
where
m₀ = 3000 g,the initial mass
k = the decay constant
t = time, years.
Because the half-life is 30 years, therefore
After 60 years, the mass remaining is
Answer: 750 g

At STP (standard temperature pressure), where gas is collected, the temperature is 0°C and the pressure is 1 atm.
The ideal gas equation indicates that
Group of answer choices .The volume occupied by mole of a given gas at a given temperature and pressure is expressed as the gas's molar volume.
The most typical illustration is the molar volume of a gas at STP, which is equal to for
mole of any ideal gas at a temperature of
Kand a pressure of
atm.
Hence, the volume of the gas is .
A unit is stated to have a temperature of absolute zero and an atmospheric pressure of one atmosphere, or
atm, at standard temperature and pressure. Additionally, at STP, a mole of any gas takes up
of space. Keep in mind that this idea only applies to gases.
For experimental measurements to be established under standard conditions that allow for comparisons between various sets of data, standard temperature and pressure must be met.
