If the pressure, volume, and temperature of a gas are known, which can most likely be found by using the ideal gas law? the molar amount of the gas the partial pressure of the gas the standard temperature and pressure the molar mass

Answer : The correct option is, the molar amount of the gas.

Explanation :

Ideal gas law : In this law, the pressure, temperature, volume and moles of gas are related to each other by the simple formula.

The ideal gas equation is,

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas or molar amount of gas

R = Gas constant

According to the question, If the pressure, volume, and temperature of a gas are known then the molar amount of the gas  can be found by using the ideal gas law.

Hence, the correct option is, the molar amount of the gas.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
