Ideal gas law PV = nRT or PM = dRt ( M is molecular mass of gas ) and d is gas density
where m/ M ( m is mass of gas sample )
m = dRT / P ( 2.78 g/L ) ( 0.082 L atm/ K mole )( 310K ) / 1.2 atm =
58.9 g/mol
gas must be butane ( C4H10) has molecular mass = 58.9 g/mol
To determine the voltage of the battery above, we use Ohm's Law which relates voltage (V), current (I) and resistance (R) in a circuit. It is expressed as V = IR. We calculate as follows:
V = IR
V = .43 A ( 3.5 ohms )
V = 1.505 V
Therefore, the correct answer is option A.
