While in Europe, if you drive 123 km day, much you spend on gas in one week it gas costs 1.10 euros per liter and your car's gas mileage is 27.0mi / g * a * l ? Assume that 1 euro = 1.26 dollars.

Money spend = $103.86

Given

Distance :123 km/day

cost 1.1 euros/L

your car's gas mileage is 27.0mi / gal

Required

Money needed

Solution

Distance/week : 123 x 7 = 861 km/week

1 km = 0.621 miles, so for 861 km =

861 x 0.621 = 534.68 miles/week

Amount of gas : 534.68 miles : 27 miles/gal = 19.8 gal

1 gal = 3.785 L , so 19.8 gal =

19.8 x 3.785 = 74.94 L

Cost for euros = 74.94 x 1.1 = 82.43

Cost for dollars = 82.43 x 1.26 = $103.86

its first and third is your answer i did the qustion the fourth isnt right

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
