Gastric juice (ph 1.5) is produced by pumping hcl from blood plasma (ph 7.4) into the stomach. calculate the amount of free energy required to concentrate the h+ in 1 l of gastric juice at 37 degrees c. under cellular conditions, how many moles of atp must by hydrolyzed to provide this amount of free energy? the free energy change for atp hydrolysis under cellular conditions is about -58 kj/mol. ignore the effects of the transmembrane electrical potential.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
