Don’t really understand what you’re asking but, if you’re asking how to read a graduated cylinder:
Look at the graduated cylinder at eye level, find the meniscus, whatever the meniscus is at is your answer.
Answer:
N2 is lost from the craft 6.9% faster than O2 is lost.
Explanation:
<u>Step 1:</u> Data given
0.500 atm of N2
0.500 atm of 02
Molar mass of 02 = 2*16 g/mole = 32 g/mole
Molar mass of N2 = 2* 14 g/mole = 28g/mole
<u>Step 2:</u> Calculate the rate of loss
r1N2 / r2O2 = √(M2(02)/M1(N2)) = √(32/28) = 1.069
1.069-1)*100= 6.9%
This means N2 is lost from the craft 6.9% faster than O2 is lost.
Answer:
B
Explanation:
Molarity measures the strength of a solution. Remember, a solution is made up of two parts: the solvent (which does the dissolving) and the solute (the substance that is dissolved). The more solute there is, the higher the concentrate and therefore the higher the molarity of the solution. Thus B is the answer
