Answer:
It will take the car 13.5 minutes to travel 3.5 miles.
Answer;
= C3H5
Explanation and solution;
1 mole of CO2 contains 44 g, of which 12 g are carbon
Thus, mass of carbon in 9.32 g will be;
(12/44) × 9.32 g = 2.542 g
Mass of Hydrogen in 3.18 g of water;
= (2/18) × 3.18 g = 0.353 g
we then find the number of moles;
Moles of carbon ; 2.542 /12 = 0.2118 moles
Moles of Hydrogen = 0.353 moles
The ratios of C ; H ;
= 1 : 0.353 /0.2118
= 1 : 5/3
= 3: 5
Therefore; the empirical formula of the hydrogen carbon is; C3H5
