in this question, we will be solving for the empirical formula of the compound. So imperial California is the small list are the simplest form of formula of a compound. We're number one, we are given masses of The elements which is 79.8 g of carbon and 20.2 g of age. Next resolve where most of each element present here, moles of carbon is 79.8 g, divided by the molar mass of 12.1 g per mole. This is 6.64 mol. Next mode of hydrogen is 20.2g divided by 1.01 graham's sperm. All this is equals to 20 mol, solving for dividing this given most of the small as a number of multi identified. A subscript, You have 6.64 Divided by 6.64 x equals to one age is 20 Divided by 6.64. This is three therefore empirical formula Yes, C H three. Next we're number two we have given masses of and Yes, it was 225.9 g Oh is 74.1 grab. So mole of n is equal to the mass. 25.9 g divided by the molar mass of 14.1 g per mole. This is 1.85. Hole. That's real mode of Os equals two 74.1g divided by 16 grams per mole Is 4.63 mol. Next we divide this to the smallest number of malware and is 1.85 divided by 1.85 is one oh, is 4.63, divided by 1.85 in Sequels to 2.5. So we need to multiply this way to to have in in hold number. We have. This is too, And this is five, therefore in very California. HLA, here is and two oh five. Thank you.
