6.79 x 10⁶

Scientific Notation consists of 2 parts  

1. the first part: the first digit followed by the decimal point  

2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point  

To add/subtract, the exponents must be the same and then add/subtract the coefficient

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
