Compound a contains 5.2% by mass of nitrogen as well as c, h and o. combustion of 0.0850 g of compound a gave 0.224 g of co2 and 0.0372 g of h2o. calculate the empirical formula of a?

the empirical formula is C7H13O10N

Explanation:Please see attachment for explanation

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

the atomic mass is the bottom number on the element.
