The oxygen fuel tank for NASA’s new SLS (Space Launch System) holds about 740,000 L of liquid oxygen. Liquid oxygen has a density of 1141 g/L. The oxygen will react with liquid hydrogen to produce the rocket’s thrust. Calculate the mass of hydrogen needed to completely react all the oxygen:
2H2+O2→2H2O

Liquid hydrogen has a density of 71 g/L. What is the minimum volume of liquid hydrogen needed to completely react all the liquid oxygen?

Calculate the volume (in liters) of the combined fuel tanks:

how did this get in the math section._.

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
