Expert Answer:

561 space dm cubed space of space straight a space gas space at space STP
Volume space equals space 748 space dm cubed
percent sign space change space in space pressure space equals space ?
straight P subscript 1 straight V subscript 1 space equals space straight P subscript 2 straight V subscript 2
100 cross times 10 cubed cross times 561 space equals space straight P subscript 2 space cross times space 748
straight P subscript 2 space equals space 7.5 space cross times space 10 to the power of 4 space Nm to the power of negative 2 end exponent
